PM / hibernate: Documentation: fix image_size default value
This commit updates the default value of /sys/power/image_size in the documentation. Since ac5c24ec1e983313ef0015258fba6f630e54e7cn the `image_size' value is set to about 2/5 of RAM, according to kernel/power/snapshot.c: image_size = ((totalram_pages * 2) / 5) * PAGE_SIZE; but this change was not reflected everywhere in the documentation.

net: dsa: Expose tagging protocol to user-space
There is no way for user-space to know what a given DSA network device's tagging protocol is. Expose this information through a dsa/tagging attribute which reflects the tagging protocol currently in use. This is helpful for configuration (e.g: none behaves dramatically different wrt. bridges) as well as for packet capture tools when there is not a proper Ethernet type available.

The current cpsw usage for cpsw-phy-sel is undocumented but is used for all the boards using cpsw. And cpsw-phy-sel is not really a child of the cpsw device, it lives in the system control module instead. Let's document the existing usage, and improve it a bit where we prefer to use a phandle instead of a child device for it. That way we can properly describe the hardware in dts files for things like genpd.

kconfig: do not require pkg-config on make {menu,n}config
Meelis Roos reported a {menu,n}config regression:
"I have libncurses devel package installed in the default system
location (as do 99%+ on actual developers probably) and in this
case, pkg-config is useless. pkg-config is needed only when
libraries and headers are installed in non-default locations but
it is bad to require installation of pkg-config on all the machines
where make menuconfig would be possibly run."
For {menu,n}config, do not use pkg-config if it is not installed.
For {g,x}config, keep checking pkg-config since we really rely on it
for finding the installation paths of the required packages.

rcu: Compute jiffies_till_sched_qs from other kernel parameters
The jiffies_till_sched_qs value used to determine how old a grace period must be before RCU enlists the help of the scheduler to force a quiescent state on the holdout CPU. Currently, this defaults to HZ/10 regardless of system size and may be set only at boot time. This can be a problem for very large systems, because if the values of the jiffies_till_first_fqs and jiffies_till_next_fqs kernel parameters are left at their defaults, they are calculated to increase as the number of CPUs actually configured on the system increases. Thus, on a sufficiently large system, RCU would enlist the help of the scheduler before the grace-period kthread had a chance to scan for idle CPUs, which wastes CPU time. This commit therefore allows jiffies_till_sched_qs to be set, if desired, but if left as default, computes is as jiffies_till_first_fqs plus twice jiffies_till_next_fqs, thus allowing three force-quiescent-state scans for idle CPUs. This scales with the number of CPUs, providing sensible default values. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> |

rcu: Stop testing RCU-bh and RCU-sched
Now that the RCU-bh and RCU-sched update-side functions are simple wrappers around their RCU counterparts, there isn't a whole lot of point in testing them. This commit therefore removes the self-test capability and removes the corresponding kernel-boot parameters. It also updates the various rcutorture .boot files to remove the kernel boot parameters that call for testing RCU-bh and RCU-sched. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> |

rcu: Defer reporting RCU-preempt quiescent states when disabled
This commit defers reporting of RCU-preempt quiescent states at rcu_read_unlock_special() time when any of interrupts, softirq, or preemption are disabled. These deferred quiescent states are reported at a later RCU_SOFTIRQ, context switch, idle entry, or CPU-hotplug offline operation. Of course, if another RCU read-side critical section has started in the meantime, the reporting of the quiescent state will be further deferred. This also means that disabling preemption, interrupts, and/or softirqs will act as an RCU-preempt read-side critical section. This is enforced by checking preempt_count() as needed. Some special cases must be handled on an ad-hoc basis, for example, context switch is a quiescent state even though both the scheduler and do_exit() disable preemption. In these cases, additional calls to rcu_preempt_deferred_qs() override the preemption disabling. Similar logic overrides disabled interrupts in rcu_preempt_check_callbacks() because in this case the quiescent state happened just before the corresponding scheduling-clock interrupt. In theory, this change lifts a long-standing restriction that required that if interrupts were disabled across a call to rcu_read_unlock() that the matching rcu_read_lock() also be contained within that interrupts-disabled region of code. Because the reporting of the corresponding RCU-preempt quiescent state is now deferred until after interrupts have been enabled, it is no longer possible for this situation to result in deadlocks involving the scheduler's runqueue and priority-inheritance locks. This may allow some code simplification that might reduce interrupt latency a bit. Unfortunately, in practice this would also defer deboosting a low-priority task that had been subjected to RCU priority boosting, so real-time-response considerations might well force this restriction to remain in place. Because RCU-preempt grace periods are now blocked not only by RCU read-side critical sections, but also by disabling of interrupts, preemption, and softirqs, it will be possible to eliminate RCU-bh and RCU-sched in favor of RCU-preempt in CONFIG_PREEMPT=y kernels. This may require some additional plumbing to provide the network denial-of-service guarantees that have been traditionally provided by RCU-bh. Once these are in place, CONFIG_PREEMPT=n kernels will be able to fold RCU-bh into RCU-sched. This would mean that all kernels would have but one flavor of RCU, which would open the door to significant code cleanup. Moving to a single flavor of RCU would also have the beneficial effect of reducing the NOCB kthreads by at least a factor of two. Signed-off-by: Paul E.

i2c: refactor function to release a DMA safe buffer
a) rename to 'put' instead of 'release' to match 'get' when obtaining the buffer b) change the argument order to have the buffer as first argument c) add a new argument telling the function if the message was transferred. This allows the function to be used also in cases where setting up DMA failed, so the buffer needs to be freed without syncing to the message buffer. Also convert the only user.

However it doesn't mention that it is also incremented due to transitions to and from user mode which for dynticks purposes is an extended quiescent state.

xfrm: allow driver to quietly refuse offload
If the "offload" attribute is used to create an IPsec SA and the .xdo_dev_state_add() fails, the SA creation fails. However, if the "offload" attribute is used on a device that doesn't offer it, the attribute is quietly ignored and the SA is created without an offload. Along the same line of that second case, it would be good to have a way for the device to refuse to offload an SA without failing the whole SA creation. This patch adds that feature by allowing the driver to return -EOPNOTSUPP as a signal that the SA may be fine, it just can't be offloaded. This allows the user a little more flexibility in requesting offloads and not needing to know every detail at all times about each specific NIC when trying to create SAs.

xen/blkback: don't keep persistent grants too long
Persistent grants are allocated until a threshold per ring is being reached. Those grants won't be freed until the ring is being destroyed meaning there will be resources kept busy which might no longer be used. Instead of freeing only persistent grants until the threshold is reached add a timestamp and remove all persistent grants not having been in use for a minute.

ARM: SoC: late updates
A couple of late-merged changes that would be useful to get in this
merge window:
- Driver support for reset of audio complex on Meson platforms. The
audio driver went in this merge window, and these changes have been
in -next for a while (just not in our tree).
- Power management fixes for IOMMU on Rockchip platforms, getting
closer to kexec working on them, including Chromebooks.
- Another pass updating "arm,psci" -> "psci" for some properties that
have snuck in since last time it was done.

namei: allow restricted O_CREAT of FIFOs and regular files
Disallows open of FIFOs or regular files not owned by the user in world writable sticky directories, unless the owner is the same as that of the directory or the file is opened without the O_CREAT flag. The purpose is to make data spoofing attacks harder. This protection can be turned on and off separately for FIFOs and regular files via sysctl, just like the symlinks/hardlinks protection. This patch is based on Openwall's "HARDEN_FIFO" feature by Solar Designer. This is a brief list of old vulnerabilities that could have been prevented by this feature, some of them even allow for privilege escalation: CVE-2000-1134 CVE-2007-3852 CVE-2008-0525 CVE-2009-0416 CVE-2011-4834 CVE-2015-1838 CVE-2015-7442 CVE-2016-7489 This list is not meant to be complete. It's difficult to track down all vulnerabilities of this kind because they were often reported without any mention of this particular attack vector. In fact, before hardlinks/symlinks restrictions, fifos/regular files weren't the favorite vehicle to exploit them.

ARM: Device-tree updates
Business as usual -- the bulk of our changes are to devicetree files
with new hardware support, new SoCs and platforms, and new board types.
New SoCs/platforms:
- Raspberry Pi Compute Module (CM1) and IO board
- i.MX6SSL from NXP
- Renesas RZ/N1D SoC (R9A06G032), Dual Cortex-A7 with Ethernet, CAN and
PLC interfaces
- TI AM654 SoC, Quad Cortex-A53, safety subsystem with Cortex-R5
controllers, communication and PRU subsystem and lots of other
interfaces (PCIe, USB3, etc).
New boards and systems:
- Several Atmel at91-based boards from Laird
- Marvell Armada388-based Helios4 board from SolidRun
- Samsung Aires-based phones (s5pv210)
- Allwinner A64-based Pinebook laptop
In addition to the above, there's the usual amount of new devices
described on existing platforms, fixes and tweaks and new minor variants
of boards/platforms.

platform-drivers-x86 for v4.19-1
The driver for Silead touchscreen configurations has been renamed from silead_dmi to touchscreen_dmi since it starts supporting other touchscreens which require some DMI quirks. At the same release cycle it gets expanded to cover cases for Chuwi Vi10, ONDA V891W, Connect Tablet 9, Onda V820w, and Cube KNote i1101 tablets. Another bunch of changes is related to Mellanox platform code to allow user space to communicate with Mellanox for system control and monitoring purposes. The driver notifies user on hotplug device signal receiving. ASUS WMI drivers recognize lid flip action on UX360, and correctly toggles airplane mode LED. In addition the keyboard backlight toggle gets support. ThinkPad ACPI driver enables support for calculator key (on at least P52). It also has been fixed to support three characters model designators, which are used for modern laptops. Earlier the battery, marked as BAT1, on ThinkPad laptops has not been configured properly, which is fixed. On the opposite the multi-battery configurations now probed correctly. Dell SMBIOS driver starts working on some Dell servers which do not support token interface. The regression with backlight detection has also been fixed.

f2fs-for-4.19-rc1
In this round, we've tuned f2fs to improve general performance by serializing
block allocation and enhancing discard flows like fstrim which avoids user IO
contention. And we've added fsync_mode=nobarrier which gives an option to user
where it skips issuing cache_flush commands to underlying flash storage. And
there are many bug fixes related to fuzzed images, revoked atomic writes, quota
ops, and minor direct IO.
Enhancement:
- add fsync_mode=nobarrier which bypasses cache_flush command
- enhance the discarding flow which avoids user IOs and issues in LBA order
- readahead some encrypted blocks during GC
- enable in-memory inode checksum to verify the blocks if F2FS_CHECK_FS is set
- enhance nat_bits behavior
- set -o discard by default
- set REQ_RAHEAD to bio in ->readpages
Bug fixes:
- fix a corner case to corrupt atomic_writes revoking flow
- revisit i_gc_rwsem to fix race conditions
- fix some dio behaviors captured by xfstests
- correct handling errors given by quota-related failures
- add many sanity check flows to avoid fuzz test failures
- add more error number propagation to their callers
- fix several corner cases to continue fault injection w/ shutdown loop

ipc: reorganize initialization of kern_ipc_perm.seq
ipc_addid() initializes kern_ipc_perm.seq after having called idr_alloc() (within ipc_idr_alloc()). Thus a parallel semop() or msgrcv() that uses ipc_obtain_object_check() may see an uninitialized value. The patch moves the initialization of kern_ipc_perm.seq before the calls of idr_alloc(). Notes: 1) This patch has a user space visible side effect: If /proc/sys/kernel/*_next_id is used (i.e.: checkpoint/restore) and if semget()/msgget()/shmget() fails in the final step of adding the id to the rhash tree, then .._next_id is cleared. Before the patch, is remained unmodified. There is no change of the behavior after a successful ..get() call: It always clears .._next_id, there is no impact to non checkpoint/restore code as that code does not use .._next_id. 2) The patch correctly documents that after a call to ipc_idr_alloc(), the full tear-down sequence must be used. The callers of ipc_addid() do not fullfill that, i.e. more bugfixes are required. The patch is a squash of a patch from Dmitry and my own changes.

kernel/hung_task.c: allow to set checking interval separately from timeout
Currently task hung checking interval is equal to timeout, as the result hung is detected anywhere between timeout and 2*timeout. This is fine for most interactive environments, but this hurts automated testing setups (syzbot). In an automated setup we need to strictly order CPU lockup < RCU stall < workqueue lockup < task hung < silent loss, so that RCU stall is not detected as task hung and task hung is not detected as silent machine loss. The large variance in task hung detection timeout requires setting silent machine loss timeout to a very large value (e.g. if task hung is 3 mins, then silent loss need to be set to ~7 mins). The additional 3 minutes significantly reduce testing efficiency because usually we crash kernel within a minute, and this can add hours to bug localization process as it needs to do dozens of tests. Allow setting checking interval separately from timeout. This allows to set timeout to, say, 3 minutes, but checking interval to 10 secs. The interval is controlled via a new hung_task_check_interval_secs sysctl, similar to the existing hung_task_timeout_secs sysctl. The default value of 0 results in the current behavior: checking interval is equal to timeout.

/proc/meminfo: add percpu populated pages count
Currently, percpu memory only exposes allocation and utilization information via debugfs. This more or less is only really useful for understanding the fragmentation and allocation information at a per-chunk level with a few global counters. This is also gated behind a config. BPF and cgroup, for example, have seen an increase in use causing increased use of percpu memory. Let's make it easier for someone to identify how much memory is being used. This patch adds the "Percpu" stat to meminfo to more easily look up how much percpu memory is in use. This number includes the cost for all allocated backing pages and not just insight at the per a unit, per chunk level. Metadata is excluded. I think excluding metadata is fair because the backing memory scales with the numbere of cpus and can quickly outweigh the metadata. It also makes this calculation light.

mm, oom: introduce memory.oom.group
For some workloads an intervention from the OOM killer can be painful. Killing a random task can bring the workload into an inconsistent state. Historically, there are two common solutions for this problem: 1) enabling panic_on_oom, 2) using a userspace daemon to monitor OOMs and kill all outstanding processes. Both approaches have their downsides: rebooting on each OOM is an obvious waste of capacity, and handling all in userspace is tricky and requires a userspace agent, which will monitor all cgroups for OOMs. In most cases an in-kernel after-OOM cleaning-up mechanism can eliminate the necessity of enabling panic_on_oom. Also, it can simplify the cgroup management for userspace applications. This commit introduces a new knob for cgroup v2 memory controller: memory.oom.group. The knob determines whether the cgroup should be treated as an indivisible workload by the OOM killer. If set, all tasks belonging to the cgroup or to its descendants (if the memory cgroup is not a leaf cgroup) are killed together or not at all. To determine which cgroup has to be killed, we do traverse the cgroup hierarchy from the victim task's cgroup up to the OOMing cgroup (or root) and looking for the highest-level cgroup with memory.oom.group set. Tasks with the OOM protection (oom_score_adj set to -1000) are treated as an exception and are never killed. This patch doesn't change the OOM victim selection algorithm.

mm: clarify CONFIG_PAGE_POISONING and usage
The Kconfig text for CONFIG_PAGE_POISONING doesn't mention that it has to be enabled explicitly. This updates the documentation for that and adds a note about CONFIG_PAGE_POISONING to the "page_poison" command line docs. While here, change description of CONFIG_PAGE_POISONING_ZERO too, as it's not "random" data, but rather the fixed debugging value that would be used when not zeroing. Additionally removes a stray "bool" in the Kconfig.

ata: libahci_platform: add reset control support
Add support to get and control a list of resets for the device as optional and shared. These resets must be kept de-asserted until the device is enabled. This is specified as shared because some SoCs like UniPhier series have common reset controls with all ahci controller instances. However, according to Thierry's view, https://www.spinics.net/lists/linux-ide/msg55357.html some hardware-specific drivers already use their own resets, and the common reset make a path to occur double controls of resets. The ahci_platform_get_resources() can get and control the reset only when the second argument includes AHCI_PLATFORM_GET_RESETS bit.

syncconfig results in an odd behavior because CONFIG_B becomes visible
in syncconfig.
$ make allyesconfig
scripts/kconfig/conf --allyesconfig Kconfig
#
# configuration written to .config
#
$ cat .config
#
# Automatically generated file; DO NOT EDIT.
# Main menu
#
CONFIG_A=y
$ make syncconfig
scripts/kconfig/conf --syncconfig Kconfig
*
* Restart config...
*
*
* Main menu
*
a (A) [Y/n/?] y
b (B) [N/y/?] (NEW)
To detect this correctly, sym_check_expr_deps() should recurse to
not only sym->rev_dep.expr but also sym->implied.expr .
At this moment, sym_check_print_recursive() cannot distinguish
'select' and 'imply' since it does not know the precise context
where the recursive dependency has been hit. This will be solved
by the next commit.
In fact, even the document and the unit-test are confused. Using
'imply' does not solve recursive dependency since 'imply' addresses
the unmet direct dependency, which 'select' could cause.

In the documentation description, this capability's name is KVM_CAP_ARM_SET_SERROR_ESR, but in the header file this capability's name is KVM_CAP_ARM_INJECT_SERROR_ESR, so change the documentation description to make it same.

overlayfs update for 4.19
This contains two new features:
1) Stack file operations: this allows removal of several hacks from the
VFS, proper interaction of read-only open files with copy-up,
possibility to implement fs modifying ioctls properly, and others.
2) Metadata only copy-up: when file is on lower layer and only metadata is
modified (except size) then only copy up the metadata and continue to
use the data from the lower file.

Merge branch 'i2c/for-4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
- the core has now a lockless variant of i2c_smbus_xfer. Some open
coded versions of this got removed in drivers. This also enables
proper SCCB support in regmap.
- locking got a more precise naming. i2c_{un}lock_adapter() had to go,
and we know use i2c_lock_bus() consistently with flags like
I2C_LOCK_ROOT_ADAPTER and I2C_LOCK_SEGMENT to avoid ambiguity.
- the gpio fault injector got a new delicate testcase
- the bus recovery procedure got fixed to handle the new testcase
correctly
- a new quirk flag for controllers not able to handle zero length
messages together with driver updates to use it
- new drivers: FSI bus attached I2C masters, GENI I2C controller, Owl
family S900
- and a good set of driver improvements and bugfixes

Raise the minimum required gcc version to 4.6
Various architectures fail to build properly with older versions of the gcc compiler. An example from Guenter Roeck in thread [1]: > > In file included from ./include/linux/mm.h:17:0, > from ./include/linux/pid_namespace.h:7, > from ./include/linux/ptrace.h:10, > from arch/openrisc/kernel/asm-offsets.c:32: > ./include/linux/mm_types.h:497:16: error: flexible array member in otherwise empty struct > > This is just an example with gcc 4.5.1 for or32.

Minor code cleanups for PPC.
For x86 this brings in PCID emulation and CR3 caching for shadow page
tables, nested VMX live migration, nested VMCS shadowing, an optimized
IPI hypercall, and some optimizations.
ARM will come next week.
There is a semantic conflict because tip also added an .init_platform
callback to kvm.c. Please keep the initializer from this branch,
and add a call to kvmclock_init (added by tip) inside kvm_init_platform
(added here).
Also, there is a backmerge from 4.18-rc6. This is because of a
refactoring that conflicted with a relatively late bugfix and
resulted in a particularly hellish conflict. Because the conflict
was only due to unfortunate timing of the bugfix, I backmerged and
rebased the refactoring rather than force the resolution on you.

RISC-V Updates for the 4.19 Merge Window
This tag contains some major improvements to the RISC-V port, including
the necessary interrupt controller and timer support to actually make it
to userspace. Support for three devices has been added:
* Support for the ISA-mandated timers on RISC-V systems.
* Support for the ISA-mandated first-level interrupt controller on
RISC-V systems, which is handled as part of our core arch code because
it's very small and tightly tied to the ISA.
* Support for SiFive's platform-level interrupt controller, which talks
to the actual devices.
In addition to these new devices, there are a handful of cleanups all
over the RISC-V tree:
* Build fixes for various configurations
* A fix to the vDSO build's makefile so it respects CFLAGS.
* The addition of __lshrti3, a libgcc derived function necessary for
some 32-bit configurations.
* !SMP && PERF_EVENTS
* Cleanups to the arch code to remove the remnants of old versions of
the drivers that were just properly submitted.
* Some dead code from the timer driver, most of which wasn't ever
even compiled.
* Cleanups of some interrupt #defines, which are now local to the
interrupt handling code.
* Fixes to ptrace(), which while not being sufficient to fully make GDB
work are at least sufficient to get simple GDB tasks to work.
* Early printk support via RISC-V's architecturally mandated SBI console
device.
* A fix to our early debug trap handler to ensure it's always aligned.
These patches have all been through a fairly extensive review process,
but as this enables a whole pile of functionality (ie, userspace) I'm
confident we'll need to submit a few more patches. The only concrete
issues I know about are the sys_riscv_flush_icache patches, but as I
managed to screw those up on Friday I figured it'd be best to let them
bake another week.
This tag boots a Fedora root filesystem on QEMU's master branch for me,
and before this morning's rebase (from 4.18-rc8 to 4.18) it booted on
the HiFive Unleashed.
Thanks to Christoph Hellwig and the other guys at WD for getting the new
drivers in shape!

This adds support for pre-start and post-shutdown hooks for remoteproc subdevices, refactors the Qualcomm Hexagon support to allow reuse between several drivers, makes authentication in the MDT file loader optional, migrates a few format strings to use %pK and migrates the Davinci driver to use the reset framework. -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAlt3Pq8bHGJqb3JuLmFu ZGVyc3NvbkBsaW5hcm8ub3JnAAoJEAsfOT8Nma3F7WQP+wT8r4ZAZ5MBSaoQTwCi Ce9+Ixxsn64tcyYMeTnUABC3EsHA4ysilbIGtqiYzpmaJhMr87+MUWKa84SyMILA lomrfzDIWvuAX9Y2NWwOuYH8FI+syq8NuES+O5S7bMfIK7zqOho+lpiI4Q8jHOAD 6y5Ta5FyoZZsy0SmtAwoFDPHKHW2pPb0RU/Fd7UOo4oXkeusuLpeZjDLTOgwoc9/ uSNM8UG+I3mslR4GdJOAwh+C8mRyVJ16YmVrvMrKjxY+MG53D1ODIO4L39j5Vf1Y 5HdIBazXrw4InPMeijOj8OI/NNJS2Ia7TJM6UdKqRTfwQfAXg9ondlxxvXm5ghju sVwx/X/duZm8QJVWaes9iAJ7seN4gooywChqrq5I5GM09jFk2qZ8DqjfesyLjOjm V3+6JCisfUm+UZsToeM1yTjOpCKPtIFrxRRllK7gMxkLvIZ8DQRV7oRT2AD8dKfX wl7apbWXKEBjtfnqV0RrR2M2znIPPC6aGjFFdWCOYo3NTiIKDnF1qeSwVGroCKUM ey+A8dBHN39qA4qfidp/QghwHg216XbyQlUlCEnJ9bqaWGYhsZRQl31W5y3fEPWL UfXkPHjuW8Ulc3yVK8pcHP5xjgg2TF5UbODHDBp1bgUQm/vmeclx+Aa2x7GBqTaF EE2uyhQjro0EJKYFGzjklJi6 =QpCe -----END PGP SIGNATURE----- Merge tag 'rproc-v4.19' of git://github.com/andersson/remoteproc Pull remoteproc updates from Bjorn Andersson: "This adds support for pre-start and post-shutdown hooks for remoteproc subdevices, refactors the Qualcomm Hexagon support to allow reuse between several drivers, makes authentication in the MDT file loader optional, migrates a few format strings to use %pK and migrates the Davinci driver to use the reset framework" * tag 'rproc-v4.19' of git://github.com/andersson/remoteproc: remoteproc/davinci: use the reset framework remoteproc/davinci: Mark error recovery as disabled remoteproc: st_slim: replace "%p" with "%pK" remoteproc: replace "%p" with "%pK" remoteproc: qcom: fix Q6V5_WCSS dependencies remoteproc: Reset table_ptr in rproc_start() failure paths remoteproc: qcom: q6v5-pil: fix modem hang on SDM845 after axis2 clk unvote remoteproc: qcom q6v5: fix modular build remoteproc: Introduce prepare and unprepare for subdevices remoteproc: rename subdev probe and remove functions remoteproc: Make client initialize ops in rproc_subdev remoteproc: Make start and stop in subdev optional remoteproc: Rename subdev functions to start/stop remoteproc: qcom: Introduce Hexagon V5 based WCSS driver remoteproc: qcom: q6v5-pil: Use common q6v5 helpers remoteproc: qcom: adsp: Use common q6v5 helpers remoteproc: q6v5: Extract common resource handling remoteproc: qcom: mdt_loader: Make the firmware authentication optional |

Char/Misc driver patches for 4.19-rc1
Here is the bit set of char/misc drivers for 4.19-rc1
There is a lot here, much more than normal, seems like everyone is
writing new driver subsystems these days... Anyway, major things here
are:
- new FSI driver subsystem, yet-another-powerpc low-level
hardware bus
- gnss, finally an in-kernel GPS subsystem to try to tame all of
the crazy out-of-tree drivers that have been floating around
for years, combined with some really hacky userspace
implementations. This is only for GNSS receivers, but you
have to start somewhere, and this is great to see.
Other than that, there are new slimbus drivers, new coresight drivers,
new fpga drivers, and loads of DT bindings for all of these and existing
drivers.
Full details of everything is in the shortlog.
All of these have been in linux-next for a while with no reported
issues.

Staging/IIO patches for 4.19-rc1
Here are the big staging/iio patches for 4.19-rc1. Lots of churn here, with tons of cleanups happening in staging drivers, a removal of an old crypto driver that no one was using (skein), and the addition of some new IIO drivers. Also added was a "gasket" driver from Google that needs loads of work and the erofs filesystem. Even with adding all of the new drivers and a new filesystem, we are only adding about 1000 lines overall to the kernel linecount, which shows just how much cleanup happened, and how big the unused crypto driver was. All of these have been in the linux-next tree for a while now with no reported issues. Note, you will have a merge problem with a device tree IIO file and the MAINTAINERS file, both resolutions are easy, just take all changed. There will be a skein file merge issue as well, but that file got deleted so just drop that.

USB/PHY patches for 4.19-rc1
Here is the big USB and phy driver patch set for 4.19-rc1.
Nothing huge but there was a lot of work that happened this development
cycle:
- lots of type-c work, with drivers graduating out of staging,
and displayport support being added.
- new PHY drivers
- the normal collection of gadget driver updates and fixes
- code churn to work on the urb handling path, using irqsave()
everywhere in anticipation of making this codepath a lot
simpler in the future.
- usbserial driver fixes and reworks
- other misc changes
Full details are in the shortlog.
All of these have been in linux-next with no reported issues for a
while.

tools/vm/page-types.c: include shared map counts
Add a new flag that will read kpagecount for each PFN and print out the number of times the page is mapped along with the flags in the listing view. This information is useful in understanding and optimizing memory usage. Identifying pages which are not shared allows us to focus on adjusting the memory layout or access patterns for the sole owning process. Knowing the number of processes that share a page tells us how many other times we must make the same adjustments or how many processes to potentially disable.

fs/seq_file.c: simplify seq_file iteration code and interface
The documentation for seq_file suggests that it is necessary to be able to move the iterator to a given offset, however that is not the case. If the iterator is stored in the private data and is stable from one read() syscall to the next, it is only necessary to support first/next interactions. Implementing this in a client is a little clumsy. - if ->start() is given a pos of zero, it should go to start of sequence. - if ->start() is given the name pos that was given to the most recent next() or start(), it should restore the iterator to state just before that last call - if ->start is given another number, it should set the iterator one beyond the start just before the last ->start or ->next call. Also, the documentation says that the implementation can interpret the pos however it likes (other than zero meaning start), but seq_file increments the pos sometimes which does impose on the implementation. This patch simplifies the interface for first/next iteration and simplifies the code, while maintaining complete backward compatability. Now: - if ->start() is given a pos of zero, it should return an iterator placed at the start of the sequence - if ->start() is given a non-zero pos, it should return the iterator in the same state it was after the last ->start or ->next. This is particularly useful for interators which walk the multiple chains in a hash table, e.g. using rhashtable_walk*. See fs/gfs2/glock.c and drivers/staging/lustre/lustre/llite/vvp_dev.c A large part of achieving this is to *always* call ->next after ->show has successfully stored all of an entry in the buffer. Never just increment the index instead. Also: - always pass &m->index to ->start() and ->next(), never a temp variable - don't clear ->from when ->count is zero, as ->from is dead when ->count is zero. Some ->next functions do not increment *pos when they return NULL. To maintain compatability with this, we still need to increment m->index in one place, if ->next didn't increment it. Note that such ->next functions are buggy and should be fixed. A simple demonstration is dd if=/proc/swaps bs=1000 skip=1 Choose any block size larger than the size of /proc/swaps. This will always show the whole last line of /proc/swaps. This patch doesn't work around buggy next() functions for this case.

powerpc updates for 4.19
Notable changes:
- A fix for a bug in our page table fragment allocator, where a page table page
could be freed and reallocated for something else while still in use, leading
to memory corruption etc. The fix reuses pt_mm in struct page (x86 only) for
a powerpc only refcount.
- Fixes to our pkey support. Several are user-visible changes, but bring us in
to line with x86 behaviour and/or fix outright bugs. Thanks to Florian Weimer
for reporting many of these.
- A series to improve the hvc driver & related OPAL console code, which have
been seen to cause hardlockups at times. The hvc driver changes in particular
have been in linux-next for ~month.
- Increase our MAX_PHYSMEM_BITS to 128TB when SPARSEMEM_VMEMMAP=y.
- Remove Power8 DD1 and Power9 DD1 support, neither chip should be in use
anywhere other than as a paper weight.
- An optimised memcmp implementation using Power7-or-later VMX instructions
- Support for barrier_nospec on some NXP CPUs.
- Support for flushing the count cache on context switch on some IBM CPUs
(controlled by firmware), as a Spectre v2 mitigation.
- A series to enhance the information we print on unhandled signals to bring it
into line with other arches, including showing the offending VMA and dumping
the instructions around the fault.

netfilter: doc: Add nf_tables part in tproxy.txt
Recently, transparent proxy support has been added to nf_tables so that this document should be updated with the new information. - Nft commands are added as alternatives to iptables ones. - The link for a patched iptables is removed as it is already part of the mainline iptables implementation (and the link is dead). - tcprdr is added as an example implementation of a transparent proxy Cc: "David S.

This is mostly updates to the usual drivers: mpt3sas, lpfc, qla2xxx, hisi_sas, smartpqi, megaraid_sas, arcmsr. In addition, with the continuing absence of Nic we have target updates for tcmu and target core (all with reviews and acks).

The new and exciting feature this time around is in the clk core.
We've added duty cycle support to the clk API so that clk signal
duty cycle ratios can be adjusted while taking into account things
like clk dividers and clk tree hierarchy. So far only one SoC has
implemented support for this, but I expect there will be more to
come in the future.
Outside of the core, we have the usual pile of clk driver updates
and additions. The Amlogic meson driver got the most lines in the
diffstat this time around because it added support for a whole bunch
of hardware and duty cycle configuration. After that the Rockchip PX30,
Qualcomm SDM845, and Renesas SoC drivers fill in a majority of the diff.
We're left with the collection of non-critical fixes after that. Overall
it looks pretty quiet this time.
Core:
- Clk duty cycle support
- Proper CLK_SET_RATE_GATE support throughout the tree
New Drivers:
- Actions Semi Owl series S700 SoC clk driver
- Qualcomm SDM845 display clock controller
- i.MX6SX ocram_s clk support
- Uniphier NAND, USB3 PHY, and SPI clk support
- Qualcomm RPMh clk driver
- i.MX7D mailbox clk support
- Maxim 9485 Programmable Clock Generator
- Expose 32 kHz PLL on PXA SoCs
- imx6sll GPIO clk gate support

- Allwinner A64 display engine clock support
- Support for Rockchip's PX30 SoC
- Amlogic Meson axg PCIe and audio clocks
- Amlogic Meson GEN CLK on gxbb, gxl and axg
Updates:
- Remove an unused variable from Exynos4412 ISP driver
- Fix a thinko bug in SCMI clk division logic
- Add missing of_node_put()s in some i.MX clk drivers
- Tegra SDMMC clk jitter improvements with high speed signaling modes
- SPDX tagging for qcom and cs2000-cp drivers
- Stop leaking con ids in __clk_put()
- Fix a corner case in fixed factor clk probing where node is in DT but
parent clk is registered much later
- Marvell Armada 3700 clk_pm_cpu_get_parent() had an invalid return value
- i.MX clk init arrays removed in place of CLK_IS_CRITICAL
- Convert to CLK_IS_CRITICAL for i.MX51/53 driver
- Fix Tegra BPMP driver oops when xlating a NULL clk
- Proper default configuration for vic03 and vde clks on Tegra124
- Mark Tegra memory controller clks as critical
- Fix array bounds clamp in Tegra's emc determine_rate() op
- Ingenic i2s bit update and allow UDC clk to gate
- Fix name of aspeed SDC clk define to have only one 'CLK'
- Fix i.MX6QDL video clk parent
- Critical clk markings for qcom SDM845
- Fix Stratix10 mpu_free_clk and sdmmc_free_clk parents
- Mark Rockchip's pclk_rkpwm_pmu as critical clock, due to it supplying
the pwm used to drive the logic supply of the rk3399 core.

This is the bulk of GPIO changes for the v4.19 kernel cycle:
Core changes: - Add a new API for explicitly naming GPIO consumers, when needed. - Don't let userspace set values on input lines. While we do not think anyone would do this crazy thing we better plug the hole before someone uses it and think it's a nifty feature. - Avoid calling chip->request() for unused GPIOs. New drivers/subdrivers: - The Mediatek MT7621 is supported which is a big win for OpenWRT and similar router distributions using this chip, as it seems every major router manufacturer on the planet has made products using this chip: https://wikidevi.com/wiki/MediaTek_MT7621 - The Tegra 194 is now supported. - The IT87 driver now supports IT8786E and IT8718F super-IO chips. - Add support for Rockchip RK3328 in the syscon GPIO driver. Driver changes: - Handle the get/set_multiple() properly on MMIO chips with inverted direction registers. We didn't have this problem until a new chip appear that has get/set registers AND inverted direction bits, OK now we handle it. - A patch series making more error codes percolate upward properly for different errors on gpiochip_lock_as_irq(). - Get/set multiple for the OMAP driver, accelerating these multiple line operations if possible. - A coprocessor interface for the Aspeed driver. Sometimes a few GPIO lines need to be grabbed by a co-processor for doing automated tasks, sometimes they are available as GPIO lines. By adding an explicit API in this driver we make it possible for the two line consumers to coexist. (This work was made available on the ib-aspeed branch, which may be appearing in other pull requests.) - Implemented .get_direction() and open drain in the SCH311x driver. - Continuing cleanup of included headers in GPIO drivers. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJbdDIRAAoJEEEQszewGV1zSVcP/j+dj4HL6R1l8nK4pSqDhY++ Sz7TS5sg7IKa5uLQa7fiheOWllwxJy/gwZ73GjHDxbkT3pol2MlL8ByxC9u7gmm8 4N4xpW0gxO5vMbkbwVj/BdL6qN//JNiwlfp+RtHO74rjUIBgc2At1qL6vul5FEPm T1HUuyzpZ/jd/+CyGR4kg1FrvncMUrStQOdKWN4pI8qFEzFfsGXSeJ+GCBSCjYwD A2Ybad6uuBfdTjrWp2AV4GpKmdKwFeQPzPjm8/CKi97nyeOckNYjDJ+M/1xUR+bb sghn3yJf7+FKO8Qmh+ATvjauPBuDbX5d39FgmFEJRk+ay4Uf2GviroHlwzyWjOi2 5TUaRBubTJM8wFXICCvFvoK8CYLfJEmjJjkHeL12lkkmOlzlCRtcQ0aOLFM+37Ga T7Z6uloEbFK6lT1P6Q/1pfCEUOhofWKdwlWaPxs+7slhKojVJw092wu7J+arKoX9 uLTIe9qAgi3pDRlAkZLrnNwoKTXm18K8KtTv/Uiq8n+s+JRuxA9pAoki5u242lXF ow22OnTgGE3hc2D3o4H1yUPZYoxG9H6iDdir0eEnZpp61xboj44iRgvyDu4LxajS mPOtigcu2qaCEx6EDHTgLIvlKsyQAJmsb0cZ6K4OM3EtUMDfC3WbBzs/VVF//pUa rb+6ruWdwkzXd+ZrnvBq =4+uQ -----END PGP SIGNATURE----- Merge tag 'gpio-v4.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.19 kernel cycle.

sound updates for 4.19
It's been busy summer weeks and hence lots of changes, partly for a
few new drivers and partly for a wide range of fixes.
Here are highlights:
ALSA Core:
- Fix rawmidi buffer management, code cleanup / refactoring
- Fix the SG-buffer page handling with incorrect fallback size
- Fix the stall at virmidi trigger callback with a large buffer;
also offloading and code-refactoring along with it
- Various ALSA sequencer code cleanups
ASoC:
- Deploy the standard snd_pcm_stop_xrun() helper in several drivers
- Support for providing name prefixes to generic component nodes
- Quite a few fixes for DPCM as it gains a bit wider use and more
robust testing
- Generalization of the DIO2125 support to a simple amplifier driver
- Accessory detection support for the audio graph card
- DT support for PXA AC'97 devices
- Quirks for a number of new x86 systems
- Support for AM Logic Meson, Everest ES7154, Intel systems with
RT5682, Qualcomm QDSP6 and WCD9335, Realtek RT5682 and TI TAS5707
HD-audio:
- Code refactoring in HD-audio ext codec codes to drop own classes;
preliminary works for the upcoming legacy codec support
- Generalized DRM audio component for the upcoming radeon / amdgpu
support
- Unification of mic mute-LED and GPIO support for various codecs
- Further improvement of CA0132 codec support including Recon3D
- Proper vga_switcheroo handling for AMD i-GPU

Pull LED updates from Jacek Anaszewski:
"LED triggers improvements make the biggest part of this pull request.
The most striking ones, that allowed for nice cleanups in the triggers
are:
- centralized handling of creation and removal of trigger sysfs
attributes via attribute group
- addition of module_led_trigger() helper
The other things that need to be mentioned:
New features and improvements to existing LED class drivers:
- lt3593: add DT support, switch to gpiod interface
- lm3692x: support LED sync configuration, change OF calls to fwnode
calls
- apu: modify PC Engines apu/apu2 driver to support apu3
Change in the drivers/net/can/led.c:
- mark led trigger as broken since it's in the way for the further
cleanups. It implements a subset of the netdev trigger and an Ack
is needed from someone who can actually test and confirm that the
netdev trigger works for can devices"

This is the bulk of pin control changes for v4.19:
Core changes:
- Augment pinctrl_generic_add_group() and pinmux_generic_add_function()
to return the selector for the added group/function to the caller
and augment (hopefully) all drivers to handle this.
New subdrivers:
- Qualcomm PM8998 and PM8005 are supported in the SPMI pin
control and GPIO driver.
- Intel Ice Lake PCH (platform controller hub) support.
- NXP (ex Freescale) i.MX8MQ support.
- Berlin AS370 support.
Improvements to drivers:
- Support interrupts on the Ocelot pin controller.
- Add SPI pins to the Uniphier driver.
- Define a GPIO compatible per SoC in the Tegra driver.

regulator: Changes for v4.19
The biggest set of changes in here is the addition of the Qualcomm RPMH
driver. As well as the regualtor driver itself being quite large due to
the usual involved Qualcomm regulator stuff there's also some code
shared with the arm-soc tree, a bus driver required to communicate with
the hardware that actually winds up being much larger than the regulator
driver itself and a LLCC driver that was part of the same signed tag
used with the arm-soc tree.
Other than that it's a fairly standard and quiet release, highlights
include:
- Addition of device links from regulator consumers to their
regulators, helping the core avoid dependency issues during suspend.
- Support for the entertainingly innovative suspend implementation in
the BD9571MWV.
- Support for switch regulators on the PFUZE100, this required two goes
due to backwards compatibility issues with old DTs that were
discovered.
- Support for Freescale PFUZE3001 and SocioNext UniPhier.
- The aforementioned Qualcomm RPMH driver together with the driver
changes required to support it.

Merge branch 'l1tf-final' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Merge L1 Terminal Fault fixes from Thomas Gleixner:
"L1TF, aka L1 Terminal Fault, is yet another speculative hardware
engineering trainwreck. It's a hardware vulnerability which allows
unprivileged speculative access to data which is available in the
Level 1 Data Cache when the page table entry controlling the virtual
address, which is used for the access, has the Present bit cleared or
other reserved bits set.
If an instruction accesses a virtual address for which the relevant
page table entry (PTE) has the Present bit cleared or other reserved
bits set, then speculative execution ignores the invalid PTE and loads
the referenced data if it is present in the Level 1 Data Cache, as if
the page referenced by the address bits in the PTE was still present
and accessible.
While this is a purely speculative mechanism and the instruction will
raise a page fault when it is retired eventually, the pure act of
loading the data and making it available to other speculative
instructions opens up the opportunity for side channel attacks to
unprivileged malicious code, similar to the Meltdown attack.
While Meltdown breaks the user space to kernel space protection, L1TF
allows to attack any physical memory address in the system and the
attack works across all protection domains. It allows an attack of SGX
and also works from inside virtual machines because the speculation
bypasses the extended page table (EPT) protection mechanism.
The assoicated CVEs are: CVE-2018-3615, CVE-2018-3620, CVE-2018-3646
The mitigations provided by this pull request include:
- Host side protection by inverting the upper address bits of a non
present page table entry so the entry points to uncacheable memory.
- Hypervisor protection by flushing L1 Data Cache on VMENTER.
- SMT (HyperThreading) control knobs, which allow to 'turn off' SMT
by offlining the sibling CPU threads. The knobs are available on
the kernel command line and at runtime via sysfs
- Control knobs for the hypervisor mitigation, related to L1D flush
and SMT control. The knobs are available on the kernel command line
and at runtime via sysfs
- Extensive documentation about L1TF including various degrees of
mitigations.
Thanks to all people who have contributed to this in various ways -
patches, review, testing, backporting - and the fruitful, sometimes
heated, but at the end constructive discussions.
There is work in progress to provide other forms of mitigations, which
might be less horrible performance wise for a particular kind of
workloads, but this is not yet ready for consumption due to their
complexity and limitations"

Changes for 4.19:
- Use extent maps to track pagecache page status instead of bufferhead
state.
- Refactor pagecache read and write paths to use the new iomap library
functions, which enable us to drop the old bufferhead code for
pagesize == blocksize filesystems.
- Set up parallel per-block-per-page metadata to track subpage
information that was tracked by buffer heads, which enables us to drop
the old bufferhead code for pagesize > blocksize filesystems.
- Tie a deferred ops control structure to a transaction so that we can
take advantage of an upper-level dfops without having to plumb pointer
passing through the code.
- Refactor the deferred ops code to track deferred ops as part of the
transaction structure (instead of as a separate data structure) so
that we can simplify the scoping rules around defer_ops.
- Refactor twisty delwri buffer submission code to avoid deadlocks.
- Shorten and fix indenting problems in the scrub code.
- Detect obviously bad summary counts at mount and fix them.
- Directly associate deferred ops control structure with a transaction
so that callers no longer have to manage it themselves.
- Remove a couple of IRIX-era inode macros.
- Remove the long-deprecated 'barrier' and 'nobarrier' mount options.
- Clean up the inode fork structure a bit.
- Check for bad fs summary counter values in the superblock.
- Reduce COW fork lookups during writeback.
- Refactor the deferred ops control structures into the transaction
structure, thereby eliminating the need for transaction users to
handle the deferred ops as a separate data structure.
- Add the ability to repair AG headers online.
- Fix a crash due to insufficient return value checking.
- Various fixes and cleanups.

Merge tag 'xfs-4.19-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Darrick Wong:
"This is the second part of the XFS changes for 4.19.
The biggest changes are the removal of buffer heads frm XFS, a massive
reworking of the deferred transaction operations handling code, the
removal of the long defunct barrier/nobarrier mount options, and the
addition of a few more online repair functions.
Summary:
- Use extent maps to track pagecache page status instead of
bufferhead state.
- Refactor pagecache read and write paths to use the new iomap
library functions, which enable us to drop the old bufferhead code
for pagesize == blocksize filesystems.

Here are the main MIPS changes for 4.19.
An overview of the general architecture changes:
- Massive DMA ops refactoring from Christoph Hellwig (huzzah for
deleting crufty code!).
- We introduce NT_MIPS_DSP & NT_MIPS_FP_MODE ELF notes & corresponding
regsets to expose DSP ASE & floating point mode state respectively,
both for live debugging & core dumps.
- We better optimize our code by hard-coding cpu_has_* macros at
compile time where their values are known due to the ISA revision
that the kernel build is targeting.
- The EJTAG exception handler now better handles SMP systems, where it
was previously possible for CPUs to clobber a register value saved
by another CPU.
- Our implementation of memset() gained a couple of fixes for MIPSr6
systems to return correct values in some cases where stores fault.
- We now implement ioremap_wc() using the uncached-accelerated cache
coherency attribute where supported, which is detected during boot,
and fall back to plain uncached access where necessary. The
MIPS-specific (and unused in tree) ioremap_uncached_accelerated() &
ioremap_cacheable_cow() are removed.
- The prctl(PR_SET_FP_MODE, ...) syscall is better supported for SMP
systems by reworking the way we ensure remote CPUs that may be
running threads within the affected process switch mode.
- Systems using the MIPS Coherence Manager will now set the
MIPS_IC_SNOOPS_REMOTE flag to avoid some unnecessary cache
maintenance overhead when flushing the icache.
- A few fixes were made for building with clang/LLVM, which
now sucessfully builds kernels for many of our platforms.
- Miscellaneous cleanups all over.
And some platform-specific changes:
- ar7 gained stubs for a few clock API functions to fix build failures
for some drivers.
- ath79 gained support for a few new SoCs, a few fixes & better
gpio-keys support.
- Ci20 now exposes its SPI bus using the spi-gpio driver.
- The generic platform can now auto-detect a suitable value for
PHYS_OFFSET based upon the memory map described by the device tree,
allowing us to avoid wasting memory on page book-keeping for systems
where RAM starts at a non-zero physical address.
- Ingenic systems using the jz4740 platform code now link their
vmlinuz higher to allow for kernels of a realistic size.
- Loongson32 now builds the kernel targeting MIPSr1 rather than MIPSr2
to avoid CPU errata.
- Loongson64 gains a couple of fixes, a workaround for a write
buffering issue & support for the Loongson 3A R3.1 CPU.
- Malta now uses the piix4-poweroff driver to handle powering down.
- Microsemi Ocelot gained support for its SPI bus & NOR flash, its
second MDIO bus and can now be supported by a FIT/.itb image.
- Octeon saw a bunch of header cleanups which remove a lot of
duplicate or unused code.

"Since Martin is on vacation you get the s390 pull request from me:
- Host large page support for KVM guests. As the patches have large
impact on arch/s390/mm/ this series goes out via both the KVM and
the s390 tree.
- Add an option for no compression to the "Kernel compression mode"
menu, this will come in handy with the rework of the early boot
code.
- A large rework of the early boot code that will make life easier
for KASAN and KASLR. With the rework the bootable uncompressed
image is not generated anymore, only the bzImage is available. For
debuggung purposes the new "no compression" option is used.
- Re-enable the gcc plugins as the issue with the latent entropy
plugin is solved with the early boot code rework.
- More spectre relates changes:
+ Detect the etoken facility and remove expolines automatically.
+ Add expolines to a few more indirect branches.
- A rewrite of the common I/O layer trace points to make them
consumable by 'perf stat'.
- Add support for format-3 PCI function measurement blocks.
- Changes for the zcrypt driver:
+ Add attributes to indicate the load of cards and queues.
+ Restructure some code for the upcoming AP device support in KVM.
- Build flags improvements in various Makefiles.
- A few fixes for the kdump support.
- A couple of patches for gcc 8 compile warning cleanup.

Pull x86 cache QoS (RDT/CAR) updates from Thomas Gleixner: "Add support for pseudo-locked cache regions. Cache Allocation Technology (CAT) allows on certain CPUs to isolate a region of cache and 'lock' it. Cache pseudo-locking builds on the fact that a CPU can still read and write data pre-allocated outside its current allocated area on cache hit. With cache pseudo-locking data can be preloaded into a reserved portion of cache that no application can fill, and from that point on will only serve cache hits. The cache pseudo-locked memory is made accessible to user space where an application can map it into its virtual address space and thus have a region of memory with reduced average read latency. The locking is not perfect and gets totally screwed by WBINDV and similar mechanisms, but it provides a reasonable enhancement for certain types of latency sensitive applications. The implementation extends the current CAT mechanism and provides a generally useful exclusive CAT mode on which it builds the extra pseude-locked regions" * 'x86-cache-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (45 commits) x86/intel_rdt: Disable PMU access x86/intel_rdt: Fix possible circular lock dependency x86/intel_rdt: Make CPU information accessible for pseudo-locked regions x86/intel_rdt: Support restoration of subset of permissions x86/intel_rdt: Fix cleanup of plr structure on error x86/intel_rdt: Move pseudo_lock_region_clear() x86/intel_rdt: Limit C-states dynamically when pseudo-locking active x86/intel_rdt: Support L3 cache performance event of Broadwell x86/intel_rdt: More precise L2 hit/miss measurements x86/intel_rdt: Create character device exposing pseudo-locked region x86/intel_rdt: Create debugfs files for pseudo-locking testing x86/intel_rdt: Create resctrl debug area x86/intel_rdt: Ensure RDT cleanup on exit x86/intel_rdt: Resctrl files reflect pseudo-locked information x86/intel_rdt: Support creation/removal of pseudo-locked region x86/intel_rdt: Pseudo-lock region creation/removal core x86/intel_rdt: Discover supported platforms via prefetch disable bits x86/intel_rdt: Add utilities to test pseudo-locked region possibility x86/intel_rdt: Split resource group removal in two x86/intel_rdt: Enable entering of pseudo-locksetup mode ... |

Pull RCU updates from Thomas Gleixner:
"A large update to RCU:
Preparatory work for consolidating the RCU flavors:
- Introduce grace-period sequence numbers to the RCU-bh, RCU-preempt,
and RCU-sched flavors, replacing the old ->gpnum and ->completed
pair of fields.
This change allows lockless code to obtain the complete
grace-period state with a single READ_ONCE(), which is needed to
maintain tolerable lock contention during the upcoming
consolidation of the three RCU flavors.
Note that grace-period sequence numbers are already used by
rcu_barrier(), expedited RCU grace periods, and SRCU, and are thus
already heavily used and well-tested. Joel Fernandes contributed a
number of excellent fixes and improvements.
- Clean up some grace-period-reporting loose ends, including
improving the handling of quiescent states from offline CPUs and
fixing some false-positive WARN_ON_ONCE() invocations.
(Strictly speaking, the WARN_ON_ONCE() invocations were quite
correct, but their invariants were (harmlessly) violated by the
earlier sloppy handling of quiescent states from offline CPUs.)
In addition, improve grace-period forward-progress guarantees so as
to allow removal of fail-safe checks that required otherwise
needless lock acquisitions. Finally, add more diagnostics to help
debug the upcoming consolidation of the RCU-bh, RCU-preempt, and
RCU-sched flavors.

- SRCU updates

f2fs: support fault_type mount option
Previously, once fault injection is on, by default, all kind of faults will be injected to f2fs, if we want to trigger single or specified combined type during the test, we need to configure sysfs entry, it will be a little inconvenient to integrate sysfs configuring into testsuit, such as xfstest. So this patch introduces a new mount option 'fault_type' to assist old option 'fault_injection', with these two mount options, we can specify any fault rate/type at mount-time.

ipv6: Add icmp_echo_ignore_all support for ICMPv6
Preventing the kernel from responding to ICMP Echo Requests messages can be useful in several ways. The sysctl parameter 'icmp_echo_ignore_all' can be used to prevent the kernel from responding to IPv4 ICMP echo requests. For IPv6 pings, such a sysctl kernel parameter did not exist. Add the ability to prevent the kernel from responding to IPv6 ICMP echo requests through the use of the following sysctl parameter : /proc/sys/net/ipv6/icmp/echo_ignore_all.

PCI: Add "pci=disable_acs_redir=" parameter for peer-to-peer support
To support peer-to-peer traffic on a segment of the PCI hierarchy, we must disable the ACS redirect bits for select PCI bridges. The bridges must be selected before the devices are discovered by the kernel and the IOMMU groups created. Therefore, add a kernel command line parameter to specify devices which must have their ACS bits disabled. The new parameter takes a list of devices separated by a semicolon. Each device specified will have its ACS redirect bits disabled. This is similar to the existing 'resource_alignment' parameter. The ACS Request P2P Request Redirect, P2P Completion Redirect and P2P Egress Control bits are disabled, which is sufficient to always allow passing P2P traffic uninterrupted. The bits are set after the kernel (optionally) enables the ACS bits itself. It is also done regardless of whether the kernel or platform firmware sets the bits. If the user tries to disable the ACS redirect for a device without the ACS capability, print a warning to dmesg.

PCI: Allow specifying devices using a base bus and path of devfns
When specifying PCI devices on the kernel command line using a bus/device/function address, bus numbers can change when adding or replacing a device, changing motherboard firmware, or applying kernel parameters like "pci=assign-buses". When bus numbers change, it's likely the command line tweak will be applied to the wrong device. Therefore, it is useful to be able to specify devices with a base bus number and the path of devfns needed to get to it, similar to the "device scope" structure in the Intel VT-d spec, Section 8.3.1. Thus, we add an option to specify devices in the following format: [<domain>:]<bus>:<device>.<func>[/<device>.<func>]* The path can be any segment within the PCI hierarchy of any length and determined through the use of 'lspci -t'. When specified this way, it is less likely that a renumbered bus will result in a valid device specification and the tweak won't be applied to the wrong device.

PCI: Make specifying PCI devices in kernel parameters reusable
Separate out the code to match a PCI device with a string (typically originating from a kernel parameter) from the pci_specified_resource_alignment() function into its own helper function. While we are at it, this change fixes the kernel style of the function (fixing a number of long lines and extra parentheses). Additionally, make the analogous change to the kernel parameter documentation: Separate the description of how to specify a PCI device into its own section at the head of the "pci=" parameter. This patch should have no functional alterations.

Daniel Borkmann says:
====================
pull-request: bpf-next 2018-08-07
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add cgroup local storage for BPF programs, which provides a fast
accessible memory for storing various per-cgroup data like number
of transmitted packets, etc, from Roman.
2) Support bpf_get_socket_cookie() BPF helper in several more program
types that have a full socket available, from Andrey.
3) Significantly improve the performance of perf events which are
reported from BPF offload. Also convert a couple of BPF AF_XDP
samples overto use libbpf, both from Jakub.
4) seg6local LWT provides the End.DT6 action, which allows to
decapsulate an outer IPv6 header containing a Segment Routing Header.
Adds this action now to the seg6local BPF interface, from Mathieu.
5) Do not mark dst register as unbounded in MOV64 instruction when
both src and dst register are the same, from Arthur.
6) Define u_smp_rmb() and u_smp_wmb() to their respective barrier
instructions on arm64 for the AF_XDP sample code, from Brian.
7) Convert the tcp_client.py and tcp_server.py BPF selftest scripts
over from Python 2 to Python 3, from Jeremy.
8) Enable BTF build flags to the BPF sample code Makefile, from Taeung.
9) Remove an unnecessary rcu_read_lock() in run_lwt_bpf(), from Taehee.
10) Several improvements to the README.rst from the BPF documentation
to make it more consistent with RST format, from Tobin.
11) Replace all occurrences of strerror() by calls to strerror_r()
in libbpf and fix a FORTIFY_SOURCE build error along with it,
from Thomas.
12) Fix a bug in bpftool's get_btf() function to correctly propagate
an error via PTR_ERR(), from Yue.

gpio: syscon: rockchip: add GRF GPIO support for rk3328
In Rockchip RK3328, the output only GPIO_MUTE pin, originally for codec mute control, can also be used for general purpose. It is manipulated by the GRF_SOC_CON10 register in GRF. Aside from the GPIO_MUTE pin, the HDMI pins can also be set in the same way. Currently this GRF GPIO controller only supports the mute pin. If needed in the future, the HDMI pins support can also be added.

KVM: X86: Implement "send IPI" hypercall
Using hypercall to send IPIs by one vmexit instead of one by one for
xAPIC/x2APIC physical mode and one vmexit per-cluster for x2APIC cluster
mode. Intel guest can enter x2apic cluster mode when interrupt remmaping
is enabled in qemu, however, latest AMD EPYC still just supports xapic
mode which can get great improvement by Exit-less IPIs. This patchset
lets a guest send multicast IPIs, with at most 128 destinations per
hypercall in 64-bit mode and 64 vCPUs per hypercall in 32-bit mode.
Hardware: Xeon Skylake 2.5GHz, 2 sockets, 40 cores, 80 threads, the VM
is 80 vCPUs, IPI microbenchmark(https://lkml.org/lkml/2017/12/19/141):
x2apic cluster mode, vanilla
Dry-run: 0, 2392199 ns

Normal IPI: 223910476, 251301666 ns

kvm: nVMX: Introduce KVM_CAP_NESTED_STATE
For nested virtualization L0 KVM is managing a bit of state for L2 guests, this state can not be captured through the currently available IOCTLs. In fact the state captured through all of these IOCTLs is usually a mix of L1 and L2 state. It is also dependent on whether the L2 guest was running at the moment when the process was interrupted to save its state. With this capability, there are two new vcpu ioctls: KVM_GET_NESTED_STATE and KVM_SET_NESTED_STATE. These can be used for saving and restoring a VM that is in VMX operation.
