Here's the main documentation changes for 5.5:
- Various kerneldoc script enhancements.
- More RST conversions; those are slowing down as we run out of things to
convert, but we're a ways from done still.
- Dan's "maintainer profile entry" work landed at last. Now we just need
to get maintainers to fill in the profiles...
- A reworking of the parallel build setup to work better with a variety of
systems (and to not take over huge systems entirely in particular).
- The MAINTAINERS file is now converted to RST during the build.
Hopefully nobody ever tries to print this thing, or they will need to
load a lot of paper.
- A script and documentation making it easy for maintainers to add Link:
tags at commit time.
Also included is the removal of a bunch of spurious CR characters.

powerpc updates for 5.5
Highlights:
- Infrastructure for secure boot on some bare metal Power9 machines. The
firmware support is still in development, so the code here won't actually
activate secure boot on any existing systems.
- A change to xmon (our crash handler / pseudo-debugger) to restrict it to
read-only mode when the kernel is lockdown'ed, otherwise it's trivial to drop
into xmon and modify kernel data, such as the lockdown state.
- Support for KASLR on 32-bit BookE machines (Freescale / NXP).
- Fixes for our flush_icache_range() and __kernel_sync_dicache() (VDSO) to work
with memory ranges >4GB.
- Some reworks of the pseries CMM (Cooperative Memory Management) driver to
make it behave more like other balloon drivers and enable some cleanups of
generic mm code.
- A series of fixes to our hardware breakpoint support to properly handle
unaligned watchpoint addresses.
Plus a bunch of other smaller improvements, fixes and cleanups.

f2fs: expose main_blkaddr in sysfs
Expose in /sys/fs/f2fs/<blockdev>/main_blkaddr the block address where the main area starts. This allows user mode programs to determine: - That pinned files that are made exclusively of fully allocated 2MB segments will never be unpinned by the file system. - Where the main area starts. This is required by programs that want to verify if a file is made exclusively of 2MB f2fs segments, the alignment boundary for segments starts at this address. Testing for 2MB alignment relative to the start of the device is incorrect, because for some filesystems main_blkaddr is not at a 2MB boundary relative to the start of the device. The entry will be used when validating reliable pinning file feature proposed by "f2fs: support aligned pinned file".

PCI/ASPM: Add sysfs attributes for controlling ASPM link states
Add sysfs attributes to Endpoints and other Upstream Ports to control ASPM, Clock PM, and L1 PM Substates.

block: add iostat counters for flush requests
Requests that triggers flushing volatile writeback cache to disk (barriers) have significant effect to overall performance. Block layer has sophisticated engine for combining several flush requests into one. But there is no statistics for actual flushes executed by disk. Requests which trigger flushes usually are barriers - zero-size writes. This patch adds two iostat counters into /sys/class/block/$dev/stat and /proc/diskstats - count of completed flush requests and their total time.

watchdog: make nowayout sysfs file writable
It can be useful to delay setting the nowayout feature for a watchdog device. Moreover, not every driver (notably gpio_wdt) implements a nowayout module parameter/otherwise respects CONFIG_WATCHDOG_NOWAYOUT, and modifying those drivers carries a risk of causing a regression for someone who has two watchdog devices, sets CONFIG_WATCHDOG_NOWAYOUT and somehow relies on the gpio_wdt driver being ignorant of that (i.e., allowing one to gracefully close a gpio_wdt but not the other watchdog in the system). So instead, simply make the nowayout sysfs file writable. Obviously, setting nowayout is a one-way street.

ima: Check against blacklisted hashes for files with modsig
Asymmetric private keys are used to sign multiple files. The kernel currently supports checking against blacklisted keys. However, if the public key is blacklisted, any file signed by the blacklisted key will automatically fail signature verification. Blacklisting the public key is not fine enough granularity, as we might want to only blacklist a particular file. This patch adds support for checking against the blacklisted hash of the file, without the appended signature, based on the IMA policy. It defines a new policy option "appraise_flag=check_blacklist". In addition to the blacklisted binary hashes stored in the firmware "dbx" variable, the Linux kernel may be configured to load blacklisted binary hashes onto the .blacklist keyring as well. The following example shows how to blacklist a specific kernel module hash. $ sha256sum kernel/kheaders.ko 77fa889b35a05338ec52e51591c1b89d4c8d1c99a21251d7c22b1a8642a6bad3 kernel/kheaders.ko $ grep BLACKLIST .config CONFIG_SYSTEM_BLACKLIST_KEYRING=y CONFIG_SYSTEM_BLACKLIST_HASH_LIST="blacklist-hash-list" $ cat certs/blacklist-hash-list "bin:77fa889b35a05338ec52e51591c1b89d4c8d1c99a21251d7c22b1a8642a6bad3" Update the IMA custom measurement and appraisal policy rules (/etc/ima-policy): measure func=MODULE_CHECK template=ima-modsig appraise func=MODULE_CHECK appraise_flag=check_blacklist appraise_type=imasig|modsig After building, installing, and rebooting the kernel: 545660333 ---lswrv 0 0 \_ blacklist: bin:77fa889b35a05338ec52e51591c1b89d4c8d1c99a21251d7c22b1a8642a6bad3 measure func=MODULE_CHECK template=ima-modsig appraise func=MODULE_CHECK appraise_flag=check_blacklist appraise_type=imasig|modsig modprobe: ERROR: could not insert 'kheaders': Permission denied 10 0c9834db5a0182c1fb0cdc5d3adcf11a11fd83dd ima-sig sha256:3bc6ed4f0b4d6e31bc1dbc9ef844605abc7afdc6d81a57d77a1ec9407997c40 2 /usr/lib/modules/5.4.0-rc3+/kernel/kernel/kheaders.ko 10 82aad2bcc3fa8ed94762356b5c14838f3bcfa6a0 ima-modsig sha256:3bc6ed4f0b4d6e31bc1dbc9ef844605abc7afdc6d81a57d77a1ec9407997c40 2 /usr/lib/modules/5.4.0rc3+/kernel/kernel/kheaders.ko sha256:77fa889b3 5a05338ec52e51591c1b89d4c8d1c99a21251d7c22b1a8642a6bad3 3082029a06092a864886f70d010702a082028b30820287020101310d300b0609608648 016503040201300b06092a864886f70d01070131820264.... 10 25b72217cc1152b44b134ce2cd68f12dfb71acb3 ima-buf sha256:8b58427fedcf8f4b20bc8dc007f2e232bf7285d7b93a66476321f9c2a3aa132 b blacklisted-hash 77fa889b35a05338ec52e51591c1b89d4c8d1c99a21251d7c22b1a8642a6bad3 Signed-off-by: Nayna Jain <nayna@linux.ibm.com> [zohar@linux.ibm.com: updated patch description] Signed-off-by: Mimi Zohar <zohar@linux.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/1572492694-6520-8-git-send-email-zohar@linux.ibm.com |

x86/bugs: Add ITLB_MULTIHIT bug infrastructure
Some processors may incur a machine check error possibly resulting in an unrecoverable CPU lockup when an instruction fetch encounters a TLB multi-hit in the instruction TLB. This can occur when the page size is changed along with either the physical address or cache type. The relevant erratum can be found here: https://bugzilla.kernel.org/show_bug.cgi?id=205195 There are other processors affected for which the erratum does not fully disclose the impact. This issue affects both bare-metal x86 page tables and EPT. It can be mitigated by either eliminating the use of large pages or by using careful TLB invalidations when changing the page size in the page tables. Just like Spectre, Meltdown, L1TF and MDS, a new bit has been allocated in MSR_IA32_ARCH_CAPABILITIES (PSCHANGE_MC_NO) and will be set on CPUs which are mitigated against this issue.

thunderbolt: Add support for lane bonding
Lane bonding allows aggregating two 10/20 Gb/s (depending on the generation) lanes into a single 20/40 Gb/s bonded link. This allows sharing the full bandwidth more efficiently. In order to establish lane bonding we need to check that lane bonding is possible through link controller and that both ends of the link actually supports 2x widths. This also means that all the paths should be established through the primary port so update tb_path_alloc() to handle this as well. Lane bonding is supported starting from Falcon Ridge (2nd generation) controllers. We also expose the current speed and number of lanes under each device except the host router following similar attribute naming than USB bus. Expose speed and number of lanes for both directions to allow possibility of asymmetric link in the future. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> |

platform/mellanox: Add bootctl driver for Mellanox BlueField Soc
This commit adds the bootctl platform driver for Mellanox BlueField
Soc, which queries secure state and controls the eMMC boot partition
swapping by sending SMC calls to ATF running at EL3.
Below are the sequences of typical use case.
1. User requests boot partition swapping, which could be on-demand or
during boot-image upgrade via UEFI capsule;
2. This bootctl driver handles the request and sends SMC call
to ATF. ATF programs register BREADCRUMB0 which has value
preserved during warm reset. It also programs eMMC to swap
the boot partition;
3. After software reset (rebooting), ATF BL1 (BootRom) checks
register BREADCRUMB0 and enable watchdog if configured;
4. If booting fails, the watchdog timer will trigger rebooting.
In such case, ATF Boot ROM will switch the boot partition
back to the previous one. This is a robust feature and used
to prevent failure during boot partition upgrade.

First set of IIO new device support, cleanups and features for the 5.5 cycle
Third version with the adis rework set dropped as better to just have
a fresh version of that at some future date.
The usual mixed backs of new device support being added to drivers,
long term reworks continuing and little per driver cleanups and
features.
Also a few trivial counter subsystem tidy ups on behalf of William.
Core new feature
* Device label support. A long requested feature no one got around to
implementing before. Allows DT based provision of a 'label' that
identifies a device uniquely within a system. This differs from existing
'name' which is meant to be the part number.
New device support
* ingenic-adc
- Support for the JZ4770 SoC ADC including bindings.
* inv_mpu6050
- Add support for magnetometer in MPU925x parts.
Fiddly to do as this is actually a separate device sitting inside the
package, but with the master device being able to schedule reads etc.
Will only run if the auxiliary bus is not in use for any other devices.
Features
* ad7192
- Userspace calibration controls to do zero and full scale.
* st_lsm6dsx
- Enable latched interrupts by default for sensors events with related clear.
- Motion events and related wakeup source. This needed quite a bit of
refactoring as well.
Cleanups and minor features
* ad7192
- sysfs ABI docs
* ad7949
- Remove code to readback configuration word as driver never actually enabled
it.
- Fix incorrect xfer length. Not actually known to cause problems other
than wasted bus usage.
* adis16080
- Replace core mlock usage with local lock with more appropriate scope.
* adis16130
- Remove pointless mlock usage.
* adis16240
- Remove include of gpio.h as no gpio usage.
* atlas-ph-sensor
- Improve logical ordering of buffer predisable / postenable functions.
This is part of a longer term rework Alexandru is driving towards.
* bh1750
- Fix up a static compiler warning and make the code more readable.
- yaml conversion of binding + MAINTAINERS entry.
* bmp280
- Drop a stray newline.
* cm36651
- Drop a redundant assignment
* itg3200
- Alignment cleanup.
* max31856
- Add missing of_node and parent references, useful to identify the device.
* sc27xx_adc
- Use devm_hwspin_lock_request_specific rather than local rolled version.
* stm32-lptimer counter
- kernel-doc warning.
* stm32-timer counter
- kernel-doc warning.
- Alignment cleanup.
* sx9500
- Improve logical ordering of buffer predisable / postenable functions.
This is part of a longer term rework Alexandru is driving towards.
* tcs3414
- Improve logical ordering of buffer predisable / postenable functions.
This is part of a longer term rework Alexandru is driving towards.

Merge tag 'iio-for-5.5a-take3' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
First set of IIO new device support, cleanups and features for the 5.5 cycle
Third version with the adis rework set dropped as better to just have
a fresh version of that at some future date.
The usual mixed backs of new device support being added to drivers,
long term reworks continuing and little per driver cleanups and
features.
Also a few trivial counter subsystem tidy ups on behalf of William.
Core new feature
* Device label support. A long requested feature no one got around to
implementing before. Allows DT based provision of a 'label' that
identifies a device uniquely within a system. This differs from existing
'name' which is meant to be the part number.
New device support
* ingenic-adc
- Support for the JZ4770 SoC ADC including bindings.
* inv_mpu6050
- Add support for magnetometer in MPU925x parts.
Fiddly to do as this is actually a separate device sitting inside the
package, but with the master device being able to schedule reads etc.
Will only run if the auxiliary bus is not in use for any other devices.
Features
* ad7192
- Userspace calibration controls to do zero and full scale.
* st_lsm6dsx
- Enable latched interrupts by default for sensors events with related clear.
- Motion events and related wakeup source. This needed quite a bit of
refactoring as well.
Cleanups and minor features
* ad7192
- sysfs ABI docs
* ad7949
- Remove code to readback configuration word as driver never actually enabled
it.
- Fix incorrect xfer length. Not actually known to cause problems other
than wasted bus usage.
* adis16080
- Replace core mlock usage with local lock with more appropriate scope.
* adis16130
- Remove pointless mlock usage.
* adis16240
- Remove include of gpio.h as no gpio usage.
* atlas-ph-sensor
- Improve logical ordering of buffer predisable / postenable functions.
This is part of a longer term rework Alexandru is driving towards.
* bh1750
- Fix up a static compiler warning and make the code more readable.
- yaml conversion of binding + MAINTAINERS entry.
* bmp280
- Drop a stray newline.
* cm36651
- Drop a redundant assignment
* itg3200
- Alignment cleanup.
* max31856
- Add missing of_node and parent references, useful to identify the device.
* sc27xx_adc
- Use devm_hwspin_lock_request_specific rather than local rolled version.
* stm32-lptimer counter
- kernel-doc warning.
* stm32-timer counter
- kernel-doc warning.
- Alignment cleanup.
* sx9500
- Improve logical ordering of buffer predisable / postenable functions.
This is part of a longer term rework Alexandru is driving towards.

RDMA/srp: Add parse function for maximum initiator to target IU size
According to SRP specifications 'srp-r16a' and 'srp2r06', IOControllerProfile attributes for SRP target port include the maximum initiator to target IU size. SRP connection daemons, such as srp_daemon, can get the value from the subnet manager. The SRP connection daemon can pass this value to kernel. This patch adds a parse function for it. Upstream commit [1] enables the kernel parameter, 'use_imm_data', by default. [1] also use (8 * 1024) as the default value for kernel parameter 'max_imm_data'. With those default values, the maximum initiator to target IU size will be 8260. In case the SRPT modules, which include the in-tree 'ib_srpt.ko' module, do not support SRP-2 'immediate data' feature, the default maximum initiator to target IU size is significantly smaller than 8260. For 'ib_srpt.ko' module, which built from source before [2], the default maximum initiator to target IU is 2116. [1] introduces a regression issue for old srp targets with default kernel parameters, as the connection will be rejected because of a too large maximum initiator to target IU size. [1] commit |

drivers/tty/serial/8250: Make Aspeed VUART SIRQ polarity configurable
Make the SIRQ polarity for Aspeed AST24xx/25xx VUART configurable via sysfs. This setting need to be changed on specific host platforms depending on the selected host interface (LPC / eSPI). The setting is configurable via sysfs rather than device-tree to stay in line with other related configurable settings. On AST2500 the VUART SIRQ polarity can be auto-configured by reading a bit from a configuration register, e.g. the LPC/eSPI interface configuration bit. Tested: Verified on TYAN S7106 mainboard.

Merge branch 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity
Pull integrity updates from Mimi Zohar: "The major feature in this time is IMA support for measuring and appraising appended file signatures. In addition are a couple of bug fixes and code cleanup to use struct_size(). In addition to the PE/COFF and IMA xattr signatures, the kexec kernel image may be signed with an appended signature, using the same scripts/sign-file tool that is used to sign kernel modules. Similarly, the initramfs may contain an appended signature. This contained a lot of refactoring of the existing appended signature verification code, so that IMA could retain the existing framework of calculating the file hash once, storing it in the IMA measurement list and extending the TPM, verifying the file's integrity based on a file hash or signature (eg. xattrs), and adding an audit record containing the file hash, all based on policy. (The IMA support for appended signatures patch set was posted and reviewed 11 times.) The support for appended signature paves the way for adding other signature verification methods, such as fs-verity, based on a single system-wide policy. The file hash used for verifying the signature and the signature, itself, can be included in the IMA measurement list" * 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity: ima: ima_api: Use struct_size() in kzalloc() ima: use struct_size() in kzalloc() sefltest/ima: support appended signatures (modsig) ima: Fix use after free in ima_read_modsig() MODSIGN: make new include file self contained ima: fix freeing ongoing ahash_request ima: always return negative code for error ima: Store the measurement again when appraising a modsig ima: Define ima-modsig template ima: Collect modsig ima: Implement support for module-style appended signatures ima: Factor xattr_verify() out of ima_appraise_measurement() ima: Add modsig appraise_type option for module-style appended signatures integrity: Select CONFIG_KEYS instead of depending on it PKCS#7: Introduce pkcs7_get_digest() PKCS#7: Refactor verify_pkcs7_signature() MODSIGN: Export module signature definitions ima: initialize the "template" field with the default template |

mm, slab: extend slab/shrink to shrink all memcg caches
Currently, a value of '1" is written to /sys/kernel/slab/<slab>/shrink file to shrink the slab by flushing out all the per-cpu slabs and free slabs in partial lists. This can be useful to squeeze out a bit more memory under extreme condition as well as making the active object counts in /proc/slabinfo more accurate. This usually applies only to the root caches, as the SLUB_MEMCG_SYSFS_ON option is usually not enabled and "slub_memcg_sysfs=1" not set. Even if memcg sysfs is turned on, it is too cumbersome and impractical to manage all those per-memcg sysfs files in a real production system. So there is no practical way to shrink memcg caches. Fix this by enabling a proper write to the shrink sysfs file of the root cache to scan all the available memcg caches and shrink them as well. For a non-root memcg cache (when SLUB_MEMCG_SYSFS_ON or slub_memcg_sysfs is on), only that cache will be shrunk when written. On a 2-socket 64-core 256-thread arm64 system with 64k page after a parallel kernel build, the the amount of memory occupied by slabs before shrinking slabs were: # grep task_struct /proc/slabinfo task_struct 53137 53192 4288 61 4 : tunables 0 0 0 : slabdata 872 872 0 # grep "^S[lRU]" /proc/meminfo Slab: 3936832 kB SReclaimable: 399104 kB SUnreclaim: 3537728 kB After shrinking slabs (by echoing "1" to all shrink files): # grep "^S[lRU]" /proc/meminfo Slab: 1356288 kB SReclaimable: 263296 kB SUnreclaim: 1092992 kB # grep task_struct /proc/slabinfo task_struct 2764 6832 4288 61 4 : tunables 0 0 0 : slabdata 112 112 0 Link: http://lkml.kernel.org/r/20190723151445.7385-1-longman@redhat.com Signed-off-by: Waiman Long <longman@redhat.com> Acked-by: Roman Gushchin <guro@fb.com> Acked-by: Christoph Lameter <cl@linux.com> Cc: Pekka Enberg <penberg@kernel.org> Cc: David Rientjes <rientjes@google.com> Cc: Joonsoo Kim <iamjoonsoo.kim@lge.com> Cc: Michal Hocko <mhocko@kernel.org> Cc: Johannes Weiner <hannes@cmpxchg.org> Cc: Shakeel Butt <shakeelb@google.com> Cc: Vladimir Davydov <vdavydov.dev@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

powerpc updates for 5.4
- Initial support for running on a system with an Ultravisor, which is software
that runs below the hypervisor and protects guests against some attacks by
the hypervisor.
- Support for building the kernel to run as a "Secure Virtual Machine", ie. as
a guest capable of running on a system with an Ultravisor.
- Some changes to our DMA code on bare metal, to allow devices with medium
sized DMA masks (> 32 && < 59 bits) to use more than 2GB of DMA space.
- Support for firmware assisted crash dumps on bare metal (powernv).
- Two series fixing bugs in and refactoring our PCI EEH code.
- A large series refactoring our exception entry code to use gas macros, both
to make it more readable and also enable some future optimisations.
As well as many cleanups and other minor features & fixups.

As has been happening in previous releases, more and more individual
driver subsystem trees are ending up in here. Now if that is good or
bad I can't tell, but hopefully it makes your life easier as it's more
of an aggregation of trees together to one merge point for you.
Anyway, lots of stuff in here:

- thunderbolt driver updates
- misc driver updates
- coresight and intel_th hwtracing driver updates
- fpga driver updates
- extcon driver updates
- some dma driver updates

Staging/IIO driver patches for 5.4-rc1
Here is the big staging/iio driver update for 5.4-rc1.
Lots of churn here, with a few driver/filesystems moving out of staging
finally:
- erofs moved out of staging
- greybus core code moved out of staging
Along with that, a new filesytem has been added:
- extfat
to provide support for those devices requiring that filesystem (i.e.
transfer devices to/from windows systems or printers.)
Other than that, there a number of new IIO drivers, and lots and lots
and lots of staging driver cleanups and minor fixes as people continue
to dig into those for easy changes.
All of these have been in linux-next for a while with no reported

Power management updates for 5.4-rc1
- Rework the main suspend-to-idle control flow to avoid repeating
"noirq" device resume and suspend operations in case of spurious
wakeups from the ACPI EC and decouple the ACPI EC wakeups support
from the LPS0 _DSM support (Rafael Wysocki).
- Extend the wakeup sources framework to expose wakeup sources as
device objects in sysfs (Tri Vo, Stephen Boyd).
- Expose system suspend statistics in sysfs (Kalesh Singh).
- Introduce a new haltpoll cpuidle driver and a new matching
governor for virtualized guests wanting to do guest-side polling
in the idle loop (Marcelo Tosatti, Joao Martins, Wanpeng Li,
Stephen Rothwell).
- Fix the menu and teo cpuidle governors to allow the scheduler tick
to be stopped if PM QoS is used to limit the CPU idle state exit
latency in some cases (Rafael Wysocki).
- Increase the resolution of the play_idle() argument to microseconds
for more fine-grained injection of CPU idle cycles (Daniel Lezcano).
- Switch over some users of cpuidle notifiers to the new QoS-based
frequency limits and drop the CPUFREQ_ADJUST and CPUFREQ_NOTIFY
policy notifier events (Viresh Kumar).
- Add new cpufreq driver based on nvmem for sun50i (Yangtao Li).
- Add support for MT8183 and MT8516 to the mediatek cpufreq driver
(Andrew-sh.Cheng, Fabien Parent).
- Add i.MX8MN support to the imx-cpufreq-dt cpufreq driver (Anson
Huang).
- Add qcs404 to cpufreq-dt-platdev blacklist (Jorge Ramirez-Ortiz).
- Update the qcom cpufreq driver (among other things, to make it
easier to extend and to use kryo cpufreq for other nvmem-based
SoCs) and add qcs404 support to it (Niklas Cassel, Douglas
RAILLARD, Sibi Sankar, Sricharan R).
- Fix assorted issues and make assorted minor improvements in the
cpufreq code (Colin Ian King, Douglas RAILLARD, Florian Fainelli,
Gustavo Silva, Hariprasad Kelam).
- Add new devfreq driver for NVidia Tegra20 (Dmitry Osipenko, Arnd
Bergmann).
- Add new Exynos PPMU events to devfreq events and extend that
mechanism (Lukasz Luba).
- Fix and clean up the exynos-bus devfreq driver (Kamil Konieczny).
- Improve devfreq documentation and governor code, fix spelling
typos in devfreq (Ezequiel Garcia, Krzysztof Kozlowski, Leonard
Crestez, MyungJoo Ham, Gaël PORTAY).
- Add regulators enable and disable to the OPP (operating performance

Pull power management updates from Rafael Wysocki:
"These include a rework of the main suspend-to-idle code flow (related
to the handling of spurious wakeups), a switch over of several users
of cpufreq notifiers to QoS-based limits, a new devfreq driver for
Tegra20, a new cpuidle driver and governor for virtualized guests, an
extension of the wakeup sources framework to expose wakeup sources as
device objects in sysfs, and more.
Specifics:
- Rework the main suspend-to-idle control flow to avoid repeating
"noirq" device resume and suspend operations in case of spurious
wakeups from the ACPI EC and decouple the ACPI EC wakeups support
from the LPS0 _DSM support (Rafael Wysocki).
- Extend the wakeup sources framework to expose wakeup sources as
device objects in sysfs (Tri Vo, Stephen Boyd).
- Expose system suspend statistics in sysfs (Kalesh Singh).
- Introduce a new haltpoll cpuidle driver and a new matching governor
for virtualized guests wanting to do guest-side polling in the idle
loop (Marcelo Tosatti, Joao Martins, Wanpeng Li, Stephen Rothwell).
- Fix the menu and teo cpuidle governors to allow the scheduler tick
to be stopped if PM QoS is used to limit the CPU idle state exit
latency in some cases (Rafael Wysocki).
- Increase the resolution of the play_idle() argument to microseconds
for more fine-grained injection of CPU idle cycles (Daniel
Lezcano).
- Switch over some users of cpuidle notifiers to the new QoS-based
frequency limits and drop the CPUFREQ_ADJUST and CPUFREQ_NOTIFY
policy notifier events (Viresh Kumar).
- Add new cpufreq driver based on nvmem for sun50i (Yangtao Li).
- Add support for MT8183 and MT8516 to the mediatek cpufreq driver
(Andrew-sh.Cheng, Fabien Parent).
- Add i.MX8MN support to the imx-cpufreq-dt cpufreq driver (Anson
Huang).
- Add qcs404 to cpufreq-dt-platdev blacklist (Jorge Ramirez-Ortiz).
- Update the qcom cpufreq driver (among other things, to make it
easier to extend and to use kryo cpufreq for other nvmem-based
SoCs) and add qcs404 support to it (Niklas Cassel, Douglas
RAILLARD, Sibi Sankar, Sricharan R).
- Fix assorted issues and make assorted minor improvements in the
cpufreq code (Colin Ian King, Douglas RAILLARD, Florian Fainelli,
Gustavo Silva, Hariprasad Kelam).
- Add new devfreq driver for NVidia Tegra20 (Dmitry Osipenko, Arnd
Bergmann).
- Add new Exynos PPMU events to devfreq events and extend that
mechanism (Lukasz Luba).
- Fix and clean up the exynos-bus devfreq driver (Kamil Konieczny).
- Improve devfreq documentation and governor code, fix spelling typos
in devfreq (Ezequiel Garcia, Krzysztof Kozlowski, Leonard Crestez,
MyungJoo Ham, Gaël PORTAY).
- Add regulators enable and disable to the OPP (operating performance
points) framework (Kamil Konieczny).
- Update the OPP framework to support multiple opp-suspend properties
(Anson Huang).

It's a somewhat calmer cycle for docs this time, as the churn of the mass
RST conversion is happily mostly behind us.
- A new document on reproducible builds.
- We finally got around to zapping the documentation for hardware support
that was removed in 2004; one doesn't want to rush these things.
- The usual assortment of fixes, typo corrections, etc.
You'll still find a handful of annoying conflicts against other trees,
mostly tied to the last RST conversions; resolutions are straightforward
and the linux-next ones are good.

btf: expose BTF info through sysfs
Make .BTF section allocated and expose its contents through sysfs.
/sys/kernel/btf directory is created to contain all the BTFs present
inside kernel. Currently there is only kernel's main BTF, represented as
/sys/kernel/btf/kernel file. Once kernel modules' BTFs are supported,
each module will expose its BTF as /sys/kernel/btf/<module-name> file.
Current approach relies on a few pieces coming together:
1. pahole is used to take almost final vmlinux image (modulo .BTF and
kallsyms) and generate .BTF section by converting DWARF info into
BTF. This section is not allocated and not mapped to any segment,
though, so is not yet accessible from inside kernel at runtime.
2. objcopy dumps .BTF contents into binary file and subsequently
convert binary file into linkable object file with automatically
generated symbols _binary__btf_kernel_bin_start and
_binary__btf_kernel_bin_end, pointing to start and end, respectively,
of BTF raw data.
3. final vmlinux image is generated by linking this object file (and
kallsyms, if necessary). sysfs_btf.c then creates
/sys/kernel/btf/kernel file and exposes embedded BTF contents through
it. This allows, e.g., libbpf and bpftool access BTF info at
well-known location, without resorting to searching for vmlinux image
on disk (location of which is not standardized and vmlinux image
might not be even available in some scenarios, e.g., inside qemu
during testing).
Alternative approach using .incbin assembler directive to embed BTF
contents directly was attempted but didn't work, because sysfs_proc.o is
not re-compiled during link-vmlinux.sh stage. This is required, though,
to update embedded BTF data (initially empty data is embedded, then
pahole generates BTF info and we need to regenerate sysfs_btf.o with
updated contents, but it's too late at that point).
If BTF couldn't be generated due to missing or too old pahole,
sysfs_btf.c handles that gracefully by detecting that
_binary__btf_kernel_bin_start (weak symbol) is 0 and not creating
/sys/kernel/btf at all.
v2->v3:
- added Documentation/ABI/testing/sysfs-kernel-btf (Greg K-H);
- created proper kobject (btf_kobj) for btf directory (Greg K-H);

efi: Export Runtime Configuration Interface table to sysfs
System firmware advertises the address of the 'Runtime Configuration Interface table version 2 (RCI2)' via an EFI Configuration Table entry. This code retrieves the RCI2 table from the address and exports it to sysfs as a binary attribute 'rci2' under /sys/firmware/efi/tables directory. The approach adopted is similar to the attribute 'DMI' under /sys/firmware/dmi/tables. RCI2 table contains BIOS HII in XML format and is used to populate BIOS setup page in Dell EMC OpenManage Server Administrator tool. The BIOS setup page contains BIOS tokens which can be configured.

ima: Add modsig appraise_type option for module-style appended signatures
Introduce the modsig keyword to the IMA policy syntax to specify that a given hook should expect the file to have the IMA signature appended to it. Here is how it can be used in a rule: appraise func=KEXEC_KERNEL_CHECK appraise_type=imasig|modsig With this rule, IMA will accept either a signature stored in the extended attribute or an appended signature. For now, the rule above will behave exactly the same as if appraise_type=imasig was specified. The actual modsig implementation will be introduced separately.

intel_th: msu: Introduce buffer interface
Introduces a concept of external buffers, which is a mechanism for creating trace sinks that would receive trace data from MSC buffers and transfer it elsewhere. A external buffer can implement its own window allocation/deallocation if it has to. It must provide a callback that's used to notify it when a window fills up, so that it can then start a DMA transaction from that window 'elsewhere'. This window remains in a 'locked' state and won't be used for storing new trace data until the buffer 'unlocks' it with a provided API call, at which point the window can be used again for storing trace data. This relies on a functional "last block" interrupt, so not all versions of Trace Hub can use this feature, which does not reflect on existing users.

platform/x86: asus: Rename "fan mode" to "fan boost mode"
The Asus WMI spec indicates that the function being controlled here is called "Fan Boost Mode". The user-facing documentation also calls it this. The spec uses the term "fan mode" is used to refer to other things, including functionality expected to appear on future products. We missed this before as we are not dealing with the most readable of specs, and didn't forsee any confusion around shortening the name. Rename "fan mode" to "fan boost mode" to improve consistency with the spec and to avoid a future naming conflict. There is no interface breakage here since this has yet to be included in an official kernel release. I also updated the kernel version listed under ABI accordingly.

platform-drivers-x86 for v5.3-1
ASUS WMI driver got a big refactoring in order to support the TUF Gaming laptops. Besides that, the regression with backlight being permanently off on various EeePC laptops has been fixed. Accelerometer on HP ProBook 450 G0 shows wrong measurements due to X axis being inverted. This has been fixed. Intel PMC core driver has been extended to be ACPI enumerated if the DSDT provides device with _HID "INT33A1". This allows to convert the driver to be pure platform and support new hardware purely based on ACPI DSDT. From now on the Intel Speed Select Technology is supported thru a corresponding driver. This driver provides an access to the features of the ISST, such as Performance Profile, Core Power, Base frequency and Turbo Frequency. Mellanox platform drivers has been refactored and now extended to support more systems, including new coming ones. The OLPC XO-1.75 platform is now supported. CB4063 Beckhoff Automation board is using PMC clocks, provided via pmc_atom driver, for ethernet controllers in a way that they can't be managed by the clock driver. The quirk has been extended to cover this case. Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile the information of Chuwi Hi10 Air has been fixed to cover more models based on the same platform. Xiaomi notebooks have WMI interface enabled. Thus, the driver to support it has been provided. It required some extension of the generic WMI library, which allows to propagate opaque context to the ->probe() of the individual drivers. This release includes debugfs clean up from Greg KH for several drivers that drop return code check and make debugfs absence or failure non-fatal. Miscellaneous fixes here and there, mostly for Acer WMI and various Intel drivers. The listed below commits are duplicated due to previously pushed fixes in v5.2 cycle: - |

f2fs-for-5.3-rc1
In this round, we've introduced native swap file support which can exploit DIO, enhanced existing checkpoint=disable feature with additional mount option to tune the triggering condition, and allowed user to preallocate physical blocks in a pinned file which will be useful to avoid f2fs fragmentation in append-only workloads. In addition, we've fixed subtle quota corruption issue. Enhancement: - add swap file support which uses DIO - allocate blocks for pinned file - allow SSR and mount option to enhance checkpoint=disable - enhance IPU IOs - add more sanity checks such as memory boundary access Bug fix: - quota corruption in very corner case of error-injected SPO case - fix root_reserved on remount and some wrong counts - add missing fsck flag Some patches were also introduced to clean up ambiguous i_flags and debugging messages codes. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAl0mlKIACgkQQBSofoJI UNI2Ow//e4QxinKVdgA6F2wx0CkdSreqfzQbA1t+6pcWgzCgLfj4dpOuSp8Yu1NT aG6YFfUxjtUNN8D85WqJ+6qKt0gFBoxjQXDvvbxLFB9Xoa2XqzFrHW8xenSRHppj V63Yye5Z+Qgss65hTktgHMWSi4mUWRq76t1lFBprXm41uC036rIQCSYioztcLQCN fFi2xfkFHf7vIIg6ZrCy22wNSCWL9X6dzKftIZ6LSz+jkPGEard1D/OUYLMMQ4YG b5DS0LEWbudn1vwALPPXwTHgZuG12W581MsHUsu2FIyenGGTk7EIZfNBN6cGfIMk NsEMnanFvXp7ZYP6HQnZlSkoBRIkD2JpYh7bFxTklw4H09GJxYFksed8uqNoDRog GPcNZjKSm0wCUHe2awOhF9kRXMFnwIR7m4DNOQHH1MYmpp3ponGsbfYy3J/qLS5y Smh8pcbsttDMQ0NaWZznby2bSEv9k9R9CoqE5sKCNDnh6Ky8WjK8x6xt3wrPG6h8 jI7venvHvJbFpxAmnKDzflZrlGj95pg0j0DAk07ql/9i8YPfRrlBKv8jOo+7aRWC jIO70URGDO6R/o5XdRqx6u8DOE1JPVP+6XzsT6MdDtBlxE+TbcTPRt3RzEgmo1d3 CI0jq0IRDTDZJITmQoQKCS85OZDyaAe2iHUPwSjCEuDex5lynuY= =S2ZS -----END PGP SIGNATURE----- Merge tag 'f2fs-for-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've introduced native swap file support which can exploit DIO, enhanced existing checkpoint=disable feature with additional mount option to tune the triggering condition, and allowed user to preallocate physical blocks in a pinned file which will be useful to avoid f2fs fragmentation in append-only workloads.

Driver Core and debugfs changes for 5.3-rc1
Here is the "big" driver core and debugfs changes for 5.3-rc1
It's a lot of different patches, all across the tree due to some api
changes and lots of debugfs cleanups. Because of this, there is going
to be some merge issues with your tree at the moment, I'll follow up
with the expected resolutions to make it easier for you.
Other than the debugfs cleanups, in this set of changes we have:
- bus iteration function cleanups (will cause build warnings
with s390 and coresight drivers in your tree)
- scripts/get_abi.pl tool to display and parse Documentation/ABI
entries in a simple way
- cleanups to Documenatation/ABI/ entries to make them parse
easier due to typos and other minor things
- default_attrs use for some ktype users
- driver model documentation file conversions to .rst
- compressed firmware file loading
- deferred probe fixes
All of these have been in linux-next for a while, with a bunch of merge
issues that Stephen has been patient with me for. Other than the merge
issues, functionality is working properly in linux-next :)

mm: smaps: split PSS into components
Report separate components (anon, file, and shmem) for PSS in smaps_rollup. This helps understand and tune the memory manager behavior in consumer devices, particularly mobile devices. Many of them (e.g. chromebooks and Android-based devices) use zram for anon memory, and perform disk reads for discarded file pages. The difference in latency is large (e.g. reading a single page from SSD is 30 times slower than decompressing a zram page on one popular device), thus it is useful to know how much of the PSS is anon vs. file. All the information is already present in /proc/pid/smaps, but much more expensive to obtain because of the large size of that procfs entry. This patch also removes a small code duplication in smaps_account, which would have gotten worse otherwise. Also updated Documentation/filesystems/proc.txt (the smaps section was a bit stale, and I added a smaps_rollup section) and Documentation/ABI/testing/procfs-smaps_rollup.

It's been a relatively busy cycle for docs:
- A fair pile of RST conversions, many from Mauro. These create more
than the usual number of simple but annoying merge conflicts with other
trees, unfortunately. He has a lot more of these waiting on the wings
that, I think, will go to you directly later on.
- A new document on how to use merges and rebases in kernel repos, and one
on Spectre vulnerabilities.
- Various improvements to the build system, including automatic markup of
function() references because some people, for reasons I will never
understand, were of the opinion that :c:func:``function()`` is
unattractive and not fun to type.
- We now recommend using sphinx 1.7, but still support back to 1.4.
- Lots of smaller improvements, warning fixes, typo fixes, etc.

Power management updates for 5.3-rc1
- Improve the handling of shared ACPI power resources in the PCI
bus type layer (Mika Westerberg).
- Make the PCI layer take link delays required by the PCIe spec
into account as appropriate and avoid polling devices in D3cold
for PME (Mika Westerberg).
- Fix some corner case issues in ACPI device power management and
in the PCI bus type layer, optimiza and clean up the handling of
runtime-suspended PCI devices during system-wide transitions to
sleep states (Rafael Wysocki).
- Rework hibernation handling in the ACPI core and the PCI bus type
to resume runtime-suspended devices before hibernation (which
allows some functional problems to be avoided) and fix some ACPI
power management issues related to hiberation (Rafael Wysocki).
- Extend the operating performance points (OPP) framework to support
a wider range of devices (Rajendra Nayak, Stehpen Boyd).
- Fix issues related to genpd_virt_devs and issues with platforms
using the set_opp() callback in the OPP framework (Viresh Kumar,
Dmitry Osipenko).
- Add new cpufreq driver for Raspberry Pi (Nicolas Saenz Julienne).
- Add new cpufreq driver for imx8m and imx7d chips (Leonard Crestez).
- Fix and clean up the pcc-cpufreq, brcmstb-avs-cpufreq, s5pv210,
and armada-37xx cpufreq drivers (David Arcari, Florian Fainelli,
Paweł Chmiel, YueHaibing).
- Clean up and fix the cpufreq core (Viresh Kumar, Daniel Lezcano).
- Fix minor issue in the ACPI system sleep support code and export
one function from it (Lenny Szubowicz, Dexuan Cui).
- Clean up assorted pieces of PM code and documentation (Kefeng Wang,
Andy Shevchenko, Bart Van Assche, Greg Kroah-Hartman, Fuqian Huang,
Geert Uytterhoeven, Mathieu Malaterre, Rafael Wysocki).
- Update the pm-graph utility to v5.4 (Todd Brandt).

IOMMU Updates for Linux v5.3
Including: - Patches to make the dma-iommu code more generic so that it can be used outside of the ARM context with other IOMMU drivers. Goal is to make use of it on x86 too. - Generic IOMMU domain support for the Intel VT-d driver. This driver now makes more use of common IOMMU code to allocate default domains for the devices it handles. - An IOMMU fault reporting API to userspace. With that the IOMMU fault handling can be done in user-space, for example to forward the faults to a VM. - Better handling for reserved regions requested by the firmware. These can be 'relaxed' now, meaning that those don't prevent a device being attached to a VM. - Suspend/Resume support for the Renesas IOMMU driver. - Added support for dumping SVA related fields of the DMAR table in the Intel VT-d driver via debugfs. - A pile of smaller fixes and cleanups. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEr9jSbILcajRFYWYyK/BELZcBGuMFAl0jaOAACgkQK/BELZcB GuNYTRAAjXuNs1OX/ROJ4TByT3YBWj5BLZVMrpGx75MAEvO68a7rTdaCpGuHv09w 5JneXxA3H2O1q6JCGguLm//Dy5QycJQIn0WuaBGi5Vjo+cGe47sf48Hb6AhIoAFf exjhfmG6kL3ZzEkLU/7iJWqz+iiCBxRU0yMINJvzFFzliJkfyGWsjoruxobmUEhm XdEsdeAQFXoPMNVCDiorM+B+3VCl7BfwfhdlFrmX3fpNrMZ5ytlnPTgfJdXAGgHn DAoK8qGoyYtRnZnivn1y56M13qv5y3XvicKqx/GRKK8CyJpz/vYSBLktI5HO4tOF y/VzNg+ctDSjQgFyKIq+38k6qu4YWctyxZNObmPVpioNf9j9GaZWT97fxGzXMNS4 G7TqOeq4yxjotAOcd+DdH265uVBtGmLqk7XobigxCZ0xzGVVnmPy4oJtkWwjaMgN HtNSMPRRirjprK4BUoCiXwP8YyWZs0a93oJmh2orD406yZkHNuqLNaicu24WsKKf Ze5BsFbNUb0qYdyL7ofOugQrOvYYoWYuREiz8ClF3U4mCcOk4FJ9K2Vf1kSfKBX8 1Skz75NeSZdzXg9JcznNMuiqH2mN3lx/88xKJg3LJxEeFxU++VDMX3Z8kEmpj5w+ 9m/v+VRclUXL6g8s6QFNIlIenMknAEjtWw6hVWPhWLaULH6fR6Y= =Kvk5 -----END PGP SIGNATURE----- Merge tag 'iommu-updates-v5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull iommu updates from Joerg Roedel: - Make the dma-iommu code more generic so that it can be used outside of the ARM context with other IOMMU drivers.

Merge branch 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity
Pull integrity updates from Mimi Zohar:
"Bug fixes, code clean up, and new features:
- IMA policy rules can be defined in terms of LSM labels, making the
IMA policy dependent on LSM policy label changes, in particular LSM
label deletions. The new environment, in which IMA-appraisal is
being used, frequently updates the LSM policy and permits LSM label
deletions.
- Prevent an mmap'ed shared file opened for write from also being
mmap'ed execute. In the long term, making this and other similar
changes at the VFS layer would be preferable.
- The IMA per policy rule template format support is needed for a
couple of new/proposed features (eg. kexec boot command line
measurement, appended signatures, and VFS provided file hashes).
- Other than the "boot-aggregate" record in the IMA measuremeent
list, all other measurements are of file data. Measuring and
storing the kexec boot command line in the IMA measurement list is
the first buffer based measurement included in the measurement
list"
* 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity:

IMA: Define a new template field buf
IMA: Define a new hook to measure the kexec boot command line arguments
IMA: support for per policy rule template formats
integrity: Fix __integrity_init_keyring() section mismatch
ima: Use designated initializers for struct ima_event_data
ima: use the lsm policy update notifier
LSM: switch to blocking policy update notifiers
x86/ima: fix the Kconfig dependency for IMA_ARCH_POLICY

Merge branch 'x86-cpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 CPU feature updates from Thomas Gleixner:
"Updates for x86 CPU features:
- Support for UMWAIT/UMONITOR, which allows to use MWAIT and MONITOR
instructions in user space to save power e.g. in HPC workloads
which spin wait on synchronization points.
The maximum time a MWAIT can halt in userspace is controlled by the
kernel and can be adjusted by the sysadmin.
- Speed up the MTRR handling code on CPUs which support cache
self-snooping correctly.
On those CPUs the wbinvd() invocations can be omitted which speeds
up the MTRR setup by a factor of 50.
- Support for the new x86 vendor Zhaoxin who develops processors
based on the VIA Centaur technology.
- Prevent 'cat /proc/cpuinfo' from affecting isolated NOHZ_FULL CPUs
by sending IPIs to retrieve the CPU frequency and use the cached
values instead.
- The addition and late revert of the FSGSBASE support. The revert
was required as it turned out that the code still has hard to
diagnose issues. Yet another engineering trainwreck...
- Small fixes, cleanups, improvements and the usual new Intel CPU
family/model addons"

s390 updates for the 5.3 merge window
- Improve stop_machine wait logic: replace cpu_relax_yield call in generic
stop_machine function with a weak stop_machine_yield function. This is
overridden on s390, which yields the current cpu to the neighbouring cpu
after a couple of retries, instead of blindly giving up the cpu to the
hipervisor. This significantly improves stop_machine performance on s390 in
overcommitted scenarios.
This includes common code changes which have been Acked by Peter Zijlstra
and Thomas Gleixner.
- Improve jump label transformation speed: transform jump labels without
using stop_machine.
- Refactoring of the vfio-ccw cp handling, simplifying the code and
avoiding unneeded allocating/copying.
- Various vfio-ccw fixes (ccw translation, state machine).
- Add support for vfio-ap queue interrupt control in the guest.
This includes s390 kvm changes which have been Acked by Christian
Borntraeger.
- Add protected virtualization support for virtio-ccw.
- Enforce both CONFIG_SMP and CONFIG_HOTPLUG_CPU, which allows to remove some
code which most likely isn't working at all, besides that s390 didn't even
compile for !CONFIG_SMP.
- Support for special flagged EP11 CPRBs for zcrypt.
- Handle PCI devices with no support for new MIO instructions.
- Avoid KASAN false positives in reworked stack unwinder.
- Couple of fixes for the QDIO layer.
- Convert s390 specific documentation to ReST format.
- Let s390 crypto modules return -ENODEV instead of -EOPNOTSUPP if hardware is
missing. This way our modules behave like most other modules and which is
also what systemd's systemd-modules-load.service expects.
- Replace defconfig with performance_defconfig, so there is one config file
less to maintain.
- Remove the SCLP call home device driver, which was never useful.
- Cleanups all over the place.

habanalabs: Add debugfs node for engines status
Command submissions sent to the device are composed of command buffers which are targeted to different device engines, like DMA and compute entities. When a command submission gets stuck, knowing in which engine the stuck is, is crucial for debugging. This patch adds a debugfs node that exports this information, by displaying the engines' various registers that assemble their idle/busy status. The information retrieval is based on the is_device_idle ASIC function. The printout in this function, of the first detected busy engine, is removed because it becomes redundant in the presence of the more elaborated info of the new debugfs node.

Second set of IIO device support, features, cleanups and minor fixes for 5.3.
A few bits for the counters subsystem mixed in here as well.
There are some late breaking fixes as well, which aren't so urgent
they can't wait for the merge window.
New Device Support
* adf4371
- New driver + bindings.
- Support the adf4372 PLL. Mostly ID and bindings.
* ad8366 (note includes rework of driver needed to allow support for these).
- Support the ADL5240 variable gain amplifier (VGA).
- Support the ADA4961 digital gain amplifier (DGA).
* dps310
- New driver, in several parts from different authors for this temp
and pressure sensor.
- Includes errata workaround for a temperature reading issue.
* stk3310
- Support the stk3335, mostly ID.
Features and cleanups
* core
- drop error handling on debugfs registration.
- harden by making sure we don't overrun iio_chan_info_postfix.
* docs
- convert remaining docs to rst. At somepoint we'll fit these few
into the main IIO docs.
- improve sampling_frequency_available docs but explaining the
range form.
* ad_sigma_delta
- Drop a pointless goto.
* ad2s1210
- Drop pointless platform data null check seeing as we don't actually
use platform data anymore.
* ad7124
- Relax limitation on channel numbers to allow pseudo different channels.
- Support control of whether the input is buffered via DT.
- Use dynamic allocation for channel configuration to make it easier
to support new devices.
- YAML binding conversion.
* ad7150
- Comment tidy up.
- Consistent and simple if (ret) handling of i2c errors.
- FIELD_GET and GENMASK.
- Ternary rather than !!(condition) for readability.
- Use macros to avoid repetition of channel definitions.
* ad7606
- Add software channel config (rather that pin controlled)
- Refactor to simplify addition of new part in future.
* ad7746
- of_deivce_id table.
* ad7780
- MAINTAINERS entry
- YAML DT bindings.
* ad8366
- Stop using core mlock in favour of well scoped local lock.
- SPDX + copyright date update.
* ad9834

* adf4371
- Add support for output stage muting before lock on has occured.
* adis library
- MAINTAINERS entry to reflect that this now Alexandru's problem ;)
* adis162xx:
- Fix a slightly incorrect set of comments and print statements on
minimum supported voltage.
* adis16203
- of_device_id table.
* adis16240
- Add of_device_id table (in two parts as first patch only used it for
MODULE_DEVICE_TABLE.)
* adt7316-spi
- of_device_id table
* adxl372
- YAML DT binding conversion.
- Cleanup use of buffer callback functions (precursor to core rework).
* bh1710
- Simplify getting the i2c adapter from the client.
* dht11
- Mote to newer GPIO consumer interface.
* kxcjk-1013.c
- Add binding for sensor in display of some ultrabooks after userspace
tools updated for it not be a problem to report two similar sensors.
* imx7d
- drop unused variables.
- white space
- define instead of variable for clock frequency that is fixed.
- drop pointless error message.
* messon_saradc
- SPDX
* sps30
- MAINTAINERS entry
- YAML binding conversion.
* st_accel
- Tidy up ordering in various buffer related callbacks. This is
part of a long running effort to simplify the core code.
* stm32-dfsdm:
- Manage the resolution cleanly in triggerd modes.
- Add fast mode support which allows more flexible filter choices.
- Add a comment on the reason for a 16 bit record when technically
not 'required'.
* st_lsm6dsx
- Embed device name in the sensor_settings struct as i3c doesn't
have a convenient name field to use for this.
* xilinx-adc
- Relax constraints on supported platforms to reflect that this
can used with FPGAs on PCIe cards and hence many architectures.
* counters/ftm-quaddec
- Fix some formatting io MODULE_AUTHOR
- MAINTAINERS entry
Fixes
* tools
- fix incorrect handling of 32 bit channels.
* sca3000
- Potential endian bug that is unlikely to bite anyone (be64 host
seems unlikely for this old part).
* stm32-adc
- Add vdda-supply. On some boards it needs to be turned on to supply
the ADC. DT bindings included.
* stm32-dfsdm
- Fix output resolution to work with filter orders other than 3.
- Fix output datatype as it's signed and previously claimed not to be.

Merge tag 'iio-for-5.3b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
Second set of IIO device support, features, cleanups and minor fixes for 5.3.
A few bits for the counters subsystem mixed in here as well.
There are some late breaking fixes as well, which aren't so urgent
they can't wait for the merge window.
New Device Support
* adf4371
- New driver + bindings.
- Support the adf4372 PLL. Mostly ID and bindings.

into the main IIO docs.
- improve sampling_frequency_available docs but explaining the
range form.

power: supply: add input power and voltage limit properties
For thermal management strategy you might be interested on limit the input power for a power supply. We already have current limit but basically what we probably want is to limit power. So, introduce the input_power_limit property. Although the common use case is limit the input power, in some specific cases it is the voltage that is problematic (i.e some regulators have different efficiencies at higher voltage resulting in more heat). So introduce also the input_voltage_limit property. This happens in one Chromebook and is used on the Pixel C's thermal management strategy to effectively limit the input power to 5V 3A when the screen is on. When the screen is on, the display, the CPU, and the GPU all contribute more heat to the system than while the screen is off, and we made a tradeoff to throttle the charger in order to give more of the thermal budget to those other components. So there's nothing fundamentally broken about the hardware that would cause the Pixel C to malfunction if we were charging at 9V or 12V instead of 5V when the screen is on, i.e. if userspace doesn't change this. What would happen is that you wouldn't meet Google's skin temperature targets on the system if the charger was allowed to run at 9V or 12V with the screen on. For folks hacking on Pixel Cs (which is now outside of Google's official support window for Android) and customizing their own kernel and userspace this would be acceptable, but we wanted to expose this feature in the power supply properties because the feature does exist in the Emedded Controller firmware of the Pixel C and all of Google's Chromebooks with USB-C made since 2015 in case someone running an up to date kernel wanted to limit the charging power for thermal or other reasons. This patch exposes a new property, similar to input current limit, to re-configure the maximum voltage from the external supply at runtime based on system-level knowledge or user input.

iio: frequency: adf4371: Add support for ADF4371 PLL
The ADF4371 is a frequency synthesizer with an integrated voltage controlled oscillator (VCO) for phase-locked loops (PLLs). The ADF4371 has an integrated VCO with a fundamental output frequency ranging from 4000 MHz to 8000 MHz. In addition, the VCO frequency is connected to divide by 1, 2, 4, 8, 16, 32, or 64 circuits that allows the user to generate radio frequency (RF) output frequencies as low as 62.5 MHz at RF8x. A frequency multiplier at RF16x generates from 8 GHz to 16 GHz. A frequency quadrupler generates frequencies from 16 GHz to 32 GHz at RF32x. RFAUX8x duplicates the frequency range of RF8x or permits direct access to the VCO output. The driver takes the reference input frequency from the device tree and uses it to calculate and maximize the PFD frequency (frequency of the phase frequency detector). The PFD frequency is further used to calculate the timeouts: synthesizer lock, VCO band selection, automatic level calibration (ALC) and PLL settling time. This initial driver exposes the attributes for setting the frequency and enabling/disabling the different adf4371 channels.

platform/x86: asus-wmi: Switch fan boost mode
The WMI exposes a write-only device ID where up to three fan modes can be switched on some laptops (TUF Gaming FX505GM). There is a hotkey combination Fn-F5 that does have a fan icon, which is designed to toggle between fan modes. The DSTS of the device ID returns information about the presence of this capability and the presence of each of the two additional fan modes as a bitmask (0x01 - overboost present, 0x02 - silent present) [1]. Add a SysFS entry that reads the last written value and updates value in WMI on write and a hotkey handler that toggles the modes taking into account their availability according to DSTS. Modes: * 0x00 - normal or balanced, * 0x01 - overboost, increased fan RPM, * 0x02 - silent, decreased fan RPM [1] Link: https://lkml.org/lkml/2019/4/12/110 Signed-off-by: Yurii Pavlovskyi <yurii.pavlovskyi@gmail.com> Suggested-by: Daniel Drake <drake@endlessm.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> |

habanalabs: Allow accessing host mapped addresses via debugfs
Allows using the addr/data32 debugfs nodes to access a device VA of a host mapped memory when the IOMMU is disabled. Due to the possible large amount of a user host mapped memory, the driver doesn't maintain a database with the host addresses per device VA. When the IOMMU is disabled, this missing info is being overcome by simply using phys_to_virt(). However, this is not useful when the IOMMU is enabled, and thus the enforced limitation.

rdma: Remove nes
This driver was first merged over 10 years ago and has not seen major activity by the authors in the last 7 years. However, in that time it has been patched 150 times to adapt it to changing kernel APIs. Further, the hardware has several issues, like not supporting 64 bit DMA, that make it rather uninteresting for use with modern systems and RDMA.

iommu: Introduce IOMMU_RESV_DIRECT_RELAXABLE reserved memory regions
Introduce a new type for reserved region. This corresponds to directly mapped regions which are known to be relaxable in some specific conditions, such as device assignment use case. Well known examples are those used by USB controllers providing PS/2 keyboard emulation for pre-boot BIOS and early BOOT or RMRRs associated to IGD working in legacy mode. Since commit |

f2fs: Add option to limit required GC for checkpoint=disable
This extends the checkpoint option to allow checkpoint=disable:%u[%] This allows you to specify what how much of the disk you are willing to lose access to while mounting with checkpoint=disable. If the amount lost would be higher, the mount will return -EAGAIN. This can be given as a percent of total space, or in blocks. Currently, we need to run garbage collection until the amount of holes is smaller than the OVP space. With the new option, f2fs can mark space as unusable up front instead of requiring garbage collection until the number of holes is small enough.

The phylink conflict was between a bug fix by Russell King
to make sure we have a consistent PHY interface mode, and
a change in net-next to pull some code in phylink_resolve()
into the helper functions phylink_mac_link_{up,down}()
On the dp83867 side it's mostly overlapping changes, with
the 'net' side removing a condition that was supposed to
trigger for RGMII but because of how it was coded never
actually could trigger.

Pull x86 MDS mitigations from Thomas Gleixner:
"Microarchitectural Data Sampling (MDS) is a hardware vulnerability
which allows unprivileged speculative access to data which is
available in various CPU internal buffers. This new set of misfeatures
has the following CVEs assigned:
CVE-2018-12126 MSBDS Microarchitectural Store Buffer Data Sampling
CVE-2018-12130 MFBDS Microarchitectural Fill Buffer Data Sampling
CVE-2018-12127 MLPDS Microarchitectural Load Port Data Sampling
CVE-2019-11091 MDSUM Microarchitectural Data Sampling Uncacheable Memory
MDS attacks target microarchitectural buffers which speculatively
forward data under certain conditions. Disclosure gadgets can expose
this data via cache side channels.
Contrary to other speculation based vulnerabilities the MDS
vulnerability does not allow the attacker to control the memory target
address. As a consequence the attacks are purely sampling based, but
as demonstrated with the TLBleed attack samples can be postprocessed
successfully.
The mitigation is to flush the microarchitectural buffers on return to
user space and before entering a VM. It's bolted on the VERW
instruction and requires a microcode update. As some of the attacks
exploit data structures shared between hyperthreads, full protection
requires to disable hyperthreading. The kernel does not do that by
default to avoid breaking unattended updates.
The mitigation set comes with documentation for administrators and a
deeper technical view"

docs: livepatch: convert docs to ReST and rename to *.rst
Convert livepatch documentation to ReST format. The changes
are mostly trivial, as the documents are already on a good
shape. Just a few markup changes are needed for Sphinx to
properly parse the docs.
The conversion is actually:
- add blank lines and identation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- The in-file TOC becomes a comment, in order to skip it from the
output, as Sphinx already generates an index there.
- adjust title markups.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

Char/Misc patches for 5.2-rc1 - part 2
Here is the "real" big set of char/misc driver patches for 5.2-rc1
Loads of different driver subsystem stuff in here, all over the places:
- thunderbolt driver updates
- habanalabs driver updates
- nvmem driver updates
- extcon driver updates
- intel_th driver updates
- mei driver updates
- coresight driver updates
- soundwire driver cleanups and updates
- fastrpc driver updates
- other minor driver updates
- chardev minor fixups
Feels like this tree is getting to be a dumping ground of "small driver
subsystems" these days. Which is fine with me, if it makes things
easier for those subsystem maintainers.
All of these have been in linux-next for a while with no reported
issues.

Staging / IIO driver patches for 5.2-rc1
Here is the big staging and iio driver update for 5.2-rc1.
Lots of tiny fixes all over the staging and IIO driver trees here, along
with some new IIO drivers.
Also we ended up deleting two drivers, making this pull request remove a
few hundred thousand lines of code, always a nice thing to see. Both of
the drivers removed have been replaced with "real" drivers in their
various subsystem directories, and they will be coming to you from those
locations during this merge window.
There are some core vt/selection changes in here, that was due to some
cleanups needed for the speakup fixes. Those have all been acked by the
various subsystem maintainers (i.e. me), so those are ok.
We also added a few new drivers, for some odd hardware, giving new
developers plenty to work on with basic coding style cleanups to come in
the near future.
Other than that, nothing unusual here.
All of these have been in linux-next for a while with no reported
issues, other than an odd gcc warning for one of the new drivers that
should be fixed up soon.

Driver core/kobject patches for 5.2-rc1
Here is the "big" set of driver core patches for 5.2-rc1
There are a number of ACPI patches in here as well, as Rafael said they
should go through this tree due to the driver core changes they
required. They have all been acked by the ACPI developers.
There are also a number of small subsystem-specific changes in here, due
to some changes to the kobject core code. Those too have all been acked
by the various subsystem maintainers.
As for content, it's pretty boring outside of the ACPI changes:
- spdx cleanups
- kobject documentation updates
- default attribute groups for kobjects
- other minor kobject/driver core fixes
All have been in linux-next for a while with no reported issues.

power: supply: core: Add CHARGE_CONTROL_{START_THRESHOLD,END_THRESHOLD} properties
Add POWER_SUPPLY_PROP_CHARGE_CONTROL_START_THRESHOLD and POWER_SUPPLY_PROP_CHARGE_CONTROL_END_THRESHOLD properties, to expand the existing CHARGE_CONTROL_* properties. I am adding them in order to support a new Chrome OS device, but these properties should be general enough that they can be used on other devices. When the charge_type is "Custom", the charge controller uses the POWER_SUPPLY_PROP_CHARGE_CONTROL_* properties as configuration for some other algorithm. For example, in the use case that I am supporting, this means the battery begins charging when the percentage level drops below POWER_SUPPLY_PROP_CHARGE_CONTROL_START_THRESHOLD and charging ceases when the percentage level goes above POWER_SUPPLY_PROP_CHARGE_CONTROL_END_THRESHOLD. v5 changes: - Add the other missing CHARGE_CONTROL_* properties documentation in a separate commit - Split up adding the charge types and adding the POWER_SUPPLY_PROP_CHARGE_CONTROL_START_THRESHOLD and POWER_SUPPLY_PROP_CHARGE_CONTROL_END_THRESHOLD properties into two different commits. v4 changes: - Add documentation for the new properties, and add documentation for the the previously missing charge_control_limit and charge_control_limit_max properties.

power: supply: core: Add Standard, Adaptive, and Custom charge types
Add "Standard", "Adaptive", and "Custom" modes to the charge_type property, to expand the existing "Trickle" and "Fast" modes. I am adding them in order to support a new Chrome OS device, but these properties should be general enough that they can be used on other devices. The meaning of "Standard" is obvious, but "Adaptive" and "Custom" are more tricky: "Adaptive" means that the charge controller uses some custom algorithm to change the charge type automatically, with no configuration needed. "Custom" means that the charge controller uses the POWER_SUPPLY_PROP_CHARGE_CONTROL_* properties as configuration for some other algorithm. v5 changes: - Split up adding the charge types and adding the POWER_SUPPLY_PROP_CHARGE_CONTROL_START_THRESHOLD and POWER_SUPPLY_PROP_CHARGE_CONTROL_END_THRESHOLD properties into two different commits. v4 changes: - Add documentation for the new properties, and add documentation for the the previously missing charge_control_limit and charge_control_limit_max properties.

nvmem: core: add NVMEM_SYSFS Kconfig
Many nvmem providers are not very keen on having default sysfs nvmem entry, as most of the usecases for them are inside kernel itself. And in some cases read/writes to some areas in nvmem are restricted and trapped at secure monitor level, so accessing them from userspace would result in board reboots. This patch adds new NVMEM_SYSFS Kconfig to make binary sysfs entry an optional one. This provision will give more flexibility to users. This patch also moves existing sysfs code to a new file so that its not compiled in when its not really required.
