kbuild: support LLVM=1 to switch the default tools to Clang/LLVM
As Documentation/kbuild/llvm.rst implies, building the kernel with a full set of LLVM tools gets very verbose and unwieldy. Provide a single switch LLVM=1 to use Clang and LLVM tools instead of GCC and Binutils. You can pass it from the command line or as an environment variable. Please note LLVM=1 does not turn on the integrated assembler. You need to pass LLVM_IAS=1 to use it. When the upstream kernel is ready for the integrated assembler, I think we can make it default. We discussed what we need, and we agreed to go with a simple boolean flag that switches both target and host tools: https://lkml.org/lkml/2020/3/28/494 https://lkml.org/lkml/2020/4/3/43 Some items discussed, but not adopted: - LLVM_DIR When multiple versions of LLVM are installed, I just thought supporting LLVM_DIR=/path/to/my/llvm/bin/ might be useful. CC = $(LLVM_DIR)clang LD = $(LLVM_DIR)ld.lld ... However, we can handle this by modifying PATH. So, we decided to not do this. - LLVM_SUFFIX Some distributions (e.g. Debian) package specific versions of LLVM with naming conventions that use the version as a suffix. CC = clang$(LLVM_SUFFIX) LD = ld.lld(LLVM_SUFFIX) ... will allow a user to pass LLVM_SUFFIX=-11 to use clang-11 etc., but the suffixed versions in /usr/bin/ are symlinks to binaries in /usr/lib/llvm-#/bin/, so this can also be handled by PATH.

kbuild: replace AS=clang with LLVM_IAS=1
The 'AS' variable is unused for building the kernel. Only the remaining usage is to turn on the integrated assembler. A boolean flag is a better fit for this purpose. AS=clang was added for experts. So, I replaced it with LLVM_IAS=1, breaking the backward compatibility.

Documentation/changes: Raise minimum supported binutils version to 2.23
The currently minimum-supported binutils version 2.21 has the problem of
promoting symbols which are defined outside of a section into absolute.
According to Arvind:
binutils-2.21 and -2.22. An x86-64 defconfig will fail with
Invalid absolute R_X86_64_32S relocation: _etext
and after fixing that one, with
Invalid absolute R_X86_64_32S relocation: __end_of_kernel_reserve
Those two versions of binutils have a bug when it comes to handling
symbols defined outside of a section and binutils 2.23 has the proper
fix, see: https://sourceware.org/legacy-ml/binutils/2012-06/msg00155.html
Therefore, up to the fixed version directly, skipping the broken ones.
Currently shipping distros already have the fixed binutils version so
there should be no breakage resulting from this.
For more details about the whole thing, see the thread in Link.

"On x86" and "On SPARC" are now definition list terms, like "On PowerPC", "On other", and "On all". The Credits list is now a bulleted list, like lots of Credits lists in other files. This prevents the list from becoming a single long, unpunctuated sentence in the generated documentation.

mm/zswap: allow setting default status, compressor and allocator in Kconfig
The compressed cache for swap pages (zswap) currently needs from 1 to 3 extra kernel command line parameters in order to make it work: it has to be enabled by adding a "zswap.enabled=1" command line parameter and if one wants a different compressor or pool allocator than the default lzo / zbud combination then these choices also need to be specified on the kernel command line in additional parameters. Using a different compressor and allocator for zswap is actually pretty common as guides often recommend using the lz4 / z3fold pair instead of the default one. In such case it is also necessary to remember to enable the appropriate compression algorithm and pool allocator in the kernel config manually. Let's avoid the need for adding these kernel command line parameters and automatically pull in the dependencies for the selected compressor algorithm and pool allocator by adding an appropriate default switches to Kconfig. The default values for these options match what the code was using previously as its defaults. Signed-off-by: Maciej S.

mm, thp: track fallbacks due to failed memcg charges separately
The thp_fault_fallback and thp_file_fallback vmstats are incremented if
either the hugepage allocation fails through the page allocator or the
hugepage charge fails through mem cgroup.
This patch leaves this field untouched but adds two new fields,
thp_{fault,file}_fallback_charge, which is incremented only when the mem
cgroup charge fails.
This distinguishes between attempted hugepage allocations that fail due to
fragmentation (or low memory conditions) and those that fail due to mem
cgroup limits. That can be used to determine the impact of fragmentation
on the system by excluding faults that failed due to memcg usage.

The existing thp_fault_fallback indicates when thp attempts to allocate a hugepage but fails, or if the hugepage cannot be charged to the mem cgroup hierarchy. Extend this to shmem as well. Adds a new thp_file_fallback to complement thp_file_alloc that gets incremented when a hugepage is attempted to be allocated but fails, or if it cannot be charged to the mem cgroup hierarchy. Additionally, remove the check for CONFIG_TRANSPARENT_HUGE_PAGECACHE from shmem_alloc_hugepage() since it is only called with this configuration option.

time/namespace: Add max_time_namespaces ucount
Michael noticed that userns limit for number of time namespaces is missing.
Furthermore, time namespace introduced UCOUNT_TIME_NAMESPACES, but didn't
introduce an array member in user_table[]. It would make array's
initialisation OOB write, but by luck the user_table array has an excessive
empty member (all accesses to the array are limited with UCOUNT_COUNTS - so
it silently reuses the last free member.
Fixes user-visible regression: max_inotify_instances by reason of the
missing UCOUNT_ENTRY() has limited max number of namespaces instead of the
number of inotify instances.

powerpc updates for 5.7
- A large series from Nick for 64-bit to further rework our exception vectors,
and rewrite portions of the syscall entry/exit and interrupt return in C. The
result is much easier to follow code that is also faster in general.
- Cleanup of our ptrace code to split various parts out that had become badly
intertwined with #ifdefs over the years.
- Changes to our NUMA setup under the PowerVM hypervisor which should
hopefully avoid non-sensical topologies which can lead to warnings from the
workqueue code and other problems.
- MAINTAINERS updates to remove some of our old orphan entries and update the
status of others.
- Quite a few other small changes and fixes all over the map.

There's not much to see in the core framework this time around. Instead the
majority of the diff is the normal collection of driver additions for new SoCs
and non-critical clk data fixes and updates. The framework must be middle aged.
The two biggest directories in the diffstat show that the Qualcomm and Unisoc
support added a handful of big drivers for new SoCs but that's not really the
whole story because those new drivers tend to add large numbers of lines of clk
data. There's a handful of AT91 clk drivers added this time around too and a
bunch of improvements to drivers like the i.MX driver. All around lots of
updates and fixes in various clk drivers which is good to see.
The core framework has only one real major change which has been baking in next
for the past couple months. It fixes the framework so that it stops caching a
clk's phase when the phase clk_op returns an error. Before this change we would
consider some negative errno as a phase and that just doesn't make sense.
Core:
- Don't show clk phase when it is invalid
New Drivers:
- Add support for Unisoc SC9863A clks
- Qualcomm SM8250 RPMh and MSM8976 RPM clks
- Qualcomm SM8250 Global Clock Controller (GCC) support
- Qualcomm SC7180 Modem Clock Controller (MSS CC) support
- EHRPWM's TimeBase clock(TBCLK) for TI AM654 SoCs
- Support PMC clks on at91sam9n12, at91rm9200, sama5d3, and at91sam9g45 SoCs
Updates:
- GPU GX GDSC support on Qualcomm sc7180
- Fixes and improvements for the Marvell MMP2/MMP3 SoC clk drivers
- A series from Anson to convert i.MX8 clock bindings to json-schema
- Update i.MX pll14xx driver to include new frequency entries for pll1443x table,
and return error for invalid PLL type
- Add missing of_node_put() call for a number of i.MX clock drivers
- Drop flag CLK_IS_CRITICAL from 'A53_CORE' mux clock, as we already
have the flag on its child cpu clock
- Fix a53 cpu clock for i.MX8 drivers to get it source from ARM PLL
via CORE_SEL slice, and source from A53 CCM clk root when we need to
change ARM PLL frequency. Thus, we can support core running above
1GHz safely
- Update i.MX pfdv2 driver to check zero rate and use determine_rate for
getting the best rate
- Add CLKO2 for imx8mm, SNVS clock for imx8mn, and PXP clock for imx7d
- Remove PMC clks from Tegra clk driver
- Improved clock/reset handling for the Renesas R-Car USB2 Clock Selector
- Conversion to json-schema of the Renesas CPG/MSSR DT bindings
- Add Crypto clocks on Renesas R-Car M3-W/W+, M3-N, E3, and D3
- Add RPC (QSPI/HyperFLASH) clocks on Renesas R-Car H3, M3-W/W+, and M3-N
- Update Amlogic audio clock gate hierarchy for meson8 and gxbb
- Update Amlogic g12a spicc clock sources
- Support for Ingenic X1000 TCU clks

New tracing features:
- The ring buffer is no longer disabled when reading the trace file.
The trace_pipe file was made to be used for live tracing and reading
as it acted like the normal producer/consumer. As the trace file
would not consume the data, the easy way of handling it was to just
disable writes to the ring buffer. This came to a surprise to the
BPF folks who complained about lost events due to reading.
This is no longer an issue. If someone wants to keep the old disabling
there's a new option "pause-on-trace" that can be set.
- New set_ftrace_notrace_pid file. PIDs in this file will not be traced
by the function tracer. Similar to set_ftrace_pid, which makes the
function tracer only trace those tasks with PIDs in the file, the
set_ftrace_notrace_pid does the reverse.
- New set_event_notrace_pid file. PIDs in this file will cause events
not to be traced if triggered by a task with a matching PID.
Similar to the set_event_pid file but will not be traced.
Note, sched_waking and sched_switch events may still be trace if
one of the tasks referenced by those events contains a PID that
is allowed to be traced.
Tracing related features:
- New bootconfig option, that is attached to the initrd file.
If bootconfig is on the command line, then the initrd file
is searched looking for a bootconfig appended at the end.
- New GPU tracepoint infrastructure to help the gfx drivers to get
off debugfs (acked by Greg Kroah-Hartman)
Other minor updates and fixes.

Pull tracing updates from Steven Rostedt:
"New tracing features:
- The ring buffer is no longer disabled when reading the trace file.
The trace_pipe file was made to be used for live tracing and
reading as it acted like the normal producer/consumer. As the trace
file would not consume the data, the easy way of handling it was to
just disable writes to the ring buffer.
This came to a surprise to the BPF folks who complained about lost
events due to reading. This is no longer an issue. If someone wants
to keep the old disabling there's a new option "pause-on-trace"
that can be set.
- New set_ftrace_notrace_pid file. PIDs in this file will not be
traced by the function tracer.
Similar to set_ftrace_pid, which makes the function tracer only
trace those tasks with PIDs in the file, the set_ftrace_notrace_pid
does the reverse.
- New set_event_notrace_pid file. PIDs in this file will cause events
not to be traced if triggered by a task with a matching PID.
Similar to the set_event_pid file but will not be traced. Note,
sched_waking and sched_switch events may still be traced if one of

This is the bulk of GPIO development for the v5.7 kernel cycle.
Core and userspace API:
- The userspace API KFIFOs have been imoproved with locks that
do not block interrupts. This makes us better at getting
events to userspace without blocking or disturbing new events
arriving in the same time. This was reviewed by the KFIFO
maintainer Stefani. This is a generic improvement which
paves the road for similar improvements in other subsystems.
- We provide a new ioctl() for monitoring changes in the line
information, such as when multiple clients are taking lines
and giving them back, possibly reconfiguring them in the
process: we can now monitor that and not get stuck with stale
static information.
- An example tool 'gpio-watch' is provided to showcase this
functionality.
- Timestamps for events are switched to ktime_get_ns() which is
monotonic. We previously had a 'realtime' stamp which could
move forward and *backward* in time, which probably would just
cause silent bugs and weird behaviour. In the long run we
see two relevant timestamps: ktime_get_ns() or the timestamp
sometimes provided by the GPIO hardware itself, if that
exists.
- Device Tree overlay support for GPIO hogs. On systems that
load overlays, these overlays can now contain hogs, and will
then be respected.
- Handle pin control interaction with nonexisting pin ranges
in the GPIO library core instead of in the individual
drivers.
New drivers:
- New driver for the Mellanox BlueField 2 GPIO controller.
Driver improvements:
- Introduce the BGPIOF_NO_SET_ON_INPUT flag to the generic
MMIO GPIO library and use this flag in the MT7621 driver.
- Texas Instruments OMAP CPU power management improvements,
such as blocking of idle on pending GPIO interrupts.

ARM: devicetree updates for v5.7
Most of the commits are for additional hardware support and minor fixes
for existing machines for all the usual platforms: qcom, amlogic, at91,
gemini, mediatek, ti, socfpga, i.mx, layerscape, uniphier, rockchip,
exynos, ux500, mvebu, tegra, stm32, renesas, sunxi, broadcom, omap,
and versatile.
The conversion of binding files to machine-readable yaml format
continues, along with fixes found during the validation.
Andre Przywara takes over maintainership for the old Calxeda Highbank
platform and provides a number of updates.
The OMAP2+ platforms see a continued move from platform data into
dts files, for many devices that relied on a mix of auxiliary data
in addition to the DT description
A moderate number of new SoCs and machines are added, here is a full
list:
- Two new Qualcomm SoCs with their evaluation boards: Snapdragon 865
(SM8250) is the current high-end phone chip, and IPQ6018 is a new
WiFi-6 router chip.

- Eleven variations of the new i.MX6 TechNexion Pico board, combining
the "dwarf", "hobbit", "nymph" and "pi" baseboards with i.MX6/i.MX7
SoM carriers
- Three additional variants of the Toradex Colibri board family, all
based on versions of the NXP i.MX7.
- The Pinebook Pro laptop based on Rockchip RK3399
- Samsung S7710 Galaxy Xcover 2, a 2013 vintage Android phone based on
the ST-Ericsson u8500 platform
- DH Electronics DHCOM SoM and PDK2 rev. 400 carrier based on
STMicroelectronics stm32mp157

Here are 3 SPDX patches for 5.7-rc1. One fixes up the SPDX tag for a single driver, while the other two go through the tree and add SPDX tags for all of the .gitignore files as needed. Nothing too complex, but you will get a merge conflict with your current tree, that should be trivial to handle (one file modified by two things, one file deleted.) All 3 of these have been in linux-next for a while, with no reported issues other than the merge conflict.

Merge branch 'for-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup updates from Tejun Heo: - Christian extended clone3 so that processes can be spawned into cgroups directly. This is not only neat in terms of semantics but also avoids grabbing the global cgroup_threadgroup_rwsem for migration. - Daniel added !root xattr support to cgroupfs. Userland already uses xattrs on cgroupfs for bookkeeping. This will allow delegated cgroups to support such usages. - Prateek tried to make cpuset hotplug handling synchronous but that led to possible deadlock scenarios. Reverted. - Other minor changes including release_agent_path handling cleanup. * 'for-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: docs: cgroup-v1: Document the cpuset_v2_mode mount option Revert "cpuset: Make cpuset hotplug synchronous" cgroupfs: Support user xattrs kernfs: Add option to enable user xattrs kernfs: Add removed_size out param for simple_xattr_set kernfs: kvmalloc xattr value instead of kmalloc cgroup: Restructure release_agent_path handling selftests/cgroup: add tests for cloning into cgroups clone3: allow spawning processes into cgroups cgroup: add cgroup_may_write() helper cgroup: refactor fork helpers cgroup: add cgroup_get_from_file() helper cgroup: unify attach permission checking cpuset: Make cpuset hotplug synchronous cgroup.c: Use built-in RCU list checking kselftest/cgroup: add cgroup destruction test cgroup: Clean up css_set task traversal |

i2c_new_smbus_alert_device() and returns ERRPTR now. All in-tree
users have been converted
- in the core, a rare race condition when deleting the cdev has been
fixed. Thanks, Kevin!
- lots of driver updates. Thanks, everyone!
I also want to mention: The amount of review and testing tags given
was quite high this time. Thank you to these people, too. I hope we
can keep it like this!"

sound updates for 5.7-rc1
This became again a busy development cycle. There are a few ALSA
core updates (merely API cleanups and sparse fixes), while majority
of other changes are found in ASoC scene.
Here are some highlights:
* ALSA core:
- More helper macros for sparse warning fixes (e.g. bitwise types)
- Slight optimization of PCM OSS locks
- Make common handling for PCM / compress buffers (for SOF)
* ASoC:
- Lots of code refactoring and modernization for (still ongoing)
componentization works
- Conversion of SND_SOC_ALL_CODECS to use imply
- Continued refactoring and fixing of the Intel SOF/SST support,
including the initial (but still incomplete) SoundWire support
- SoundWire and more advanced clocking support for Realtek RT5682
- Support for amlogic GX, Meson 8, Meson 8B and T9015 DAC, Broadcom
DSL/PON, Ingenic JZ4760 and JZ4770, Realtek RL6231, and TI TAS2563
and TLV320ADCX140
* HD-audio:
- Optimizations in HDMI jack handling
- A few new quirks and fixups for Realtek codecs
* USB-audio:
- Delayed registration support
- New quirks for Motu, Kingston, Presonus

remoteproc updates for v5.7
This introduces a range of improvements to the OMAP remoeteproc driver; among other things adding devicetree, suspend/resume and watchdog support, and adds support the remoteprocs in the DRA7xx SoC. It introduces support for 64-bit firmware, extends the ELF loader to support this and fixes for a number of race conditions in the recovery handling. It introduces a generic mechanism to allow remoteproc drivers to sync state with remote processors during a panic, and uses this to prepare Qualcomm remote processors for post mortem analysis. Finally it introduces fixes to cleanly recover from crashes in the modem firmware on production Qualcomm devices. -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAl6FObEbHGJqb3JuLmFu ZGVyc3NvbkBsaW5hcm8ub3JnAAoJEAsfOT8Nma3FerQP/A4X/ONtMSwfamWseInj TRfYj5BOo6drGKavgG9NjQti2pUDfUo6wen906uRlgE48pEwToCVBZ1ERONj/pPD nsEzXWsZqDjVut9VH5Zhc+T9k+GJVlLkocu+EnpnS9uZ59ySuH/HFY0W6BoyVpuI 2ltodDq9TGHY3nFkaAz+yQKGsqB3e0RqlqCsTHnKHxeOsaG+HLyH89QPUIQzYMAJ P+CyW+h62KnlW7I0nteX3M86nmDxD1S7lQg6NK9GMiuOyVw4FyGiO3+AnX9JBue8 fFF1Z5344WT44IA7n/pjTdKtRy1R8CkwVKBzooWwpvGJo/3d3D1VcYN1S2IoNlb4 L3j3tBSexhthekZ5nBowHdfv5cbTAlWQn8GwKXDRLw4TVrV+wVdeG3kXNbhD6Ka2 sdAv5W4Eguap5dvlJqbC/d6cvQXiZOrzWogd0aqhSB6aMiyb+Pjol+kQZtNWIW1S CmvRFhlSnAwM0NLYQpXGzuaza8LvfMphG6+nwkneSD5IFclKQ+tUxmqOtt2dLqVG 9gtiqSt7fO58I4KxtQGWvp3FBa4FVeH00hF+H0Xu2B9pEsWYr9N2Ua5CDlIJdWKV OS6sVHlYB1a+E4IpJ92GEBp/KwmRJsVCNRKkbDE3Y7UNFoNoTPhnVlsdx5Sa/stT lTQPYoIKmOF8hTZEzLM4Vc7n =5Q77 -----END PGP SIGNATURE----- Merge tag 'rproc-v5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc Pull remoteproc updates from Bjorn Andersson: - a range of improvements to the OMAP remoeteproc driver; among other things adding devicetree, suspend/resume and watchdog support, and adds support the remoteprocs in the DRA7xx SoC - support for 64-bit firmware, extends the ELF loader to support this and fixes for a number of race conditions in the recovery handling - a generic mechanism to allow remoteproc drivers to sync state with remote processors during a panic, and uses this to prepare Qualcomm remote processors for post mortem analysis - fixes to cleanly recover from crashes in the modem firmware on production Qualcomm devices * tag 'rproc-v5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc: (37 commits) remoteproc/omap: Switch to SPDX license identifiers remoteproc/omap: Add watchdog functionality for remote processors remoteproc/omap: Report device exceptions and trigger recovery remoteproc/omap: Add support for runtime auto-suspend/resume remoteproc/omap: Add support for system suspend/resume remoteproc/omap: Request a timer(s) for remoteproc usage remoteproc/omap: Check for undefined mailbox messages remoteproc/omap: Remove the platform_data header remoteproc/omap: Add support for DRA7xx remote processors remoteproc/omap: Initialize and assign reserved memory node remoteproc/omap: Add the rproc ops .da_to_va() implementation remoteproc/omap: Add support to parse internal memories from DT remoteproc/omap: Add a sanity check for DSP boot address alignment remoteproc/omap: Add device tree support dt-bindings: remoteproc: Add OMAP remoteproc bindings remoteproc: qcom: Introduce panic handler for PAS and ADSP remoteproc: qcom: q6v5: Add common panic handler remoteproc: Introduce "panic" callback in ops remoteproc: Traverse rproc_list under RCU read lock remoteproc: Fix NULL pointer dereference in rproc_virtio_notify ... |

KVM/MIPS has been broken since 5.5, it does not compile due to a patch committed
by MIPS maintainers. I had already prepared a fix, but the MIPS maintainers
prefer to fix it in generic code rather than KVM so they are taking care of it.

mm: memcontrol: recursive memory.low protection
Right now, the effective protection of any given cgroup is capped by its
own explicit memory.low setting, regardless of what the parent says. The
reasons for this are mostly historical and ease of implementation: to make
delegation of memory.low safe, effective protection is the min() of all
memory.low up the tree.
Unfortunately, this limitation makes it impossible to protect an entire
subtree from another without forcing the user to make explicit protection
allocations all the way to the leaf cgroups - something that is highly
undesirable in real life scenarios.
Consider memory in a data center host. At the cgroup top level, we have a
distinction between system management software and the actual workload the
system is executing. Both branches are further subdivided into individual
services, job components etc.
We want to protect the workload as a whole from the system management
software, but that doesn't mean we want to protect and prioritize
individual workload wrt each other. Their memory demand can vary over
time, and we'd want the VM to simply cache the hottest data within the
workload subtree. Yet, the current memory.low limitations force us to
allocate a fixed amount of protection to each workload component in order
to get protection from system management software in general. This
results in very inefficient resource distribution.
Another concern with mandating downward allocation is that, as the
complexity of the cgroup tree grows, it gets harder for the lower levels
to be informed about decisions made at the host-level. Consider a
container inside a namespace that in turn creates its own nested tree of
cgroups to run multiple workloads. It'd be extremely difficult to
configure memory.low parameters in those leaf cgroups that on one hand
balance pressure among siblings as the container desires, while also
reflecting the host-level protection from e.g. rpm upgrades, that lie
beyond one or more delegation and namespacing points in the tree.
It's highly unusual from a cgroup interface POV that nested levels have to
be aware of and reflect decisions made at higher levels for them to be
effective.
To enable such use cases and scale configurability for complex trees, this
patch implements a resource inheritance model for memory that is similar
to how the CPU and the IO controller implement work-conserving resource
allocations: a share of a resource allocated to a subree always applies to
the entire subtree recursively, while allowing, but not mandating,
children to further specify distribution rules.
That means that if protection is explicitly allocated among siblings,
those configured shares are being followed during page reclaim just like
they are now. However, if the memory.low set at a higher level is not
fully claimed by the children in that subtree, the "floating" remainder is
applied to each cgroup in the tree in proportion to its size. Since
reclaim pressure is applied in proportion to size as well, each child in
that tree gets the same boost, and the effect is neutral among siblings -
with respect to each other, they behave as if no memory control was
enabled at all, and the VM simply balances the memory demands optimally
within the subtree. But collectively those cgroups enjoy a boost over the
cgroups in neighboring trees.
E.g. a leaf cgroup with a memory.low setting of 0 no longer means that
it's not getting a share of the hierarchically assigned resource, just
that it doesn't claim a fixed amount of it to protect from its siblings.
This allows us to recursively protect one subtree (workload) from another
(system management), while letting subgroups compete freely among each
other - without having to assign fixed shares to each leaf, and without
nested groups having to echo higher-level settings.
The floating protection composes naturally with fixed protection.
Consider the following example tree:
A A: low = 2G
/ \ A1: low = 1G
A1 A2 A2: low = 0G
As outside pressure is applied to this tree, A1 will enjoy a fixed
protection from A2 of 1G, but the remaining, unclaimed 1G from A is split
evenly among A1 and A2, coming out to 1.5G and 0.5G.
There is a slight risk of regressing theoretical setups where the
top-level cgroups don't know about the true budgeting and set bogusly high
"bypass" values that are meaningfully allocated down the tree. Such
setups would rely on unclaimed protection to be discarded, and
distributing it would change the intended behavior. Be safe and hide the
new behavior behind a mount option, 'memory_recursiveprot'.

mm: dump_page(): additional diagnostics for huge pinned pages
As part of pin_user_pages() and related API calls, pages are "dma-pinned". For the case of compound pages of order > 1, the per-page accounting of dma pins is accomplished via the 3rd struct page in the compound page. In order to support debugging of any pin_user_pages()- related problems, enhance dump_page() so as to report the pin count in that case.

mm/gup: /proc/vmstat: pin_user_pages (FOLL_PIN) reporting
Now that pages are "DMA-pinned" via pin_user_page*(), and unpinned via
unpin_user_pages*(), we need some visibility into whether all of this is
working correctly.
Add two new fields to /proc/vmstat:
nr_foll_pin_acquired
nr_foll_pin_released
These are documented in Documentation/core-api/pin_user_pages.rst. They
represent the number of pages (since boot time) that have been pinned
("nr_foll_pin_acquired") and unpinned ("nr_foll_pin_released"), via
pin_user_pages*() and unpin_user_pages*().
In the absence of long-running DMA or RDMA operations that hold pages
pinned, the above two fields will normally be equal to each other.
Also: update Documentation/core-api/pin_user_pages.rst, to remove an
earlier (now confirmed untrue) claim about a performance problem with
/proc/vmstat.
Also: update Documentation/core-api/pin_user_pages.rst to rename the new
/proc/vmstat entries, to the names listed here.

mm/gup: page->hpage_pinned_refcount: exact pin counts for huge pages
For huge pages (and in fact, any compound page), the GUP_PIN_COUNTING_BIAS scheme tends to overflow too easily, each tail page increments the head page->_refcount by GUP_PIN_COUNTING_BIAS (1024). That limits the number of huge pages that can be pinned. This patch removes that limitation, by using an exact form of pin counting for compound pages of order > 1. The "order > 1" is required because this approach uses the 3rd struct page in the compound page, and order 1 compound pages only have two pages, so that won't work there. A new struct page field, hpage_pinned_refcount, has been added, replacing a padding field in the union (so no new space is used). This enhancement also has a useful side effect: huge pages and compound pages (of order > 1) do not suffer from the "potential false positives" problem that is discussed in the page_dma_pinned() comment block. That is because these compound pages have extra space for tracking things, so they get exact pin counts instead of overloading page->_refcount. Documentation/core-api/pin_user_pages.rst is updated accordingly.

mm/gup: track FOLL_PIN pages
Add tracking of pages that were pinned via FOLL_PIN. This tracking is
implemented via overloading of page->_refcount: pins are added by adding
GUP_PIN_COUNTING_BIAS (1024) to the refcount. This provides a fuzzy
indication of pinning, and it can have false positives (and that's OK).
Please see the pre-existing Documentation/core-api/pin_user_pages.rst for
details.
As mentioned in pin_user_pages.rst, callers who effectively set FOLL_PIN
(typically via pin_user_pages*()) are required to ultimately free such
pages via unpin_user_page().
Please also note the limitation, discussed in pin_user_pages.rst under the
"TODO: for 1GB and larger huge pages" section. (That limitation will be
removed in a following patch.)
The effect of a FOLL_PIN flag is similar to that of FOLL_GET, and may be
thought of as "FOLL_GET for DIO and/or RDMA use".
Pages that have been pinned via FOLL_PIN are identifiable via a new
function call:
bool page_maybe_dma_pinned(struct page *page);
What to do in response to encountering such a page, is left to later
patchsets. There is discussion about this in [1], [2], [3], and [4].
This also changes a BUG_ON(), to a WARN_ON(), in follow_page_mask().

"This series focuses on corner case bug fixes and general clarity
improvements to hmm_range_fault(). It arose from a review of
hmm_range_fault() by Christoph, Ralph and myself.
hmm_range_fault() is being used by these 'SVM' style drivers to
non-destructively read the page tables. It is very similar to
get_user_pages() except that the output is an array of PFNs and
per-pfn flags, and it has various modes of reading.
This is necessary before RDMA ODP can be converted, as we don't want
to have weird corner case regressions, which is still a looking
forward item. Ralph has a nice tester for this routine, but it is
waiting for feedback from the selftests maintainers.

linux-kselftest-kunit-5.7-rc1
This kunit update for Linux-5.7-rc1 consists of:
- debugfs support for displaying kunit test suite results; this is
especially useful for module-loaded tests to allow disentangling of
test result display from other dmesg events. CONFIG_KUNIT_DEBUGFS
enables/disables the debugfs support.
- Several fixes and improvements to kunit framework and tool.

Kbuild updates for v5.7
[Build system]
- add CONFIG_UNUSED_KSYMS_WHITELIST, which will be useful to define
a fixed set of export symbols for Generic Kernel Image (GKI)
- allow to run 'make dt_binding_check' without .config
- use full schema for checking DT examples in *.yaml files
- make modpost fail for missing MODULE_IMPORT_NS(), which makes more
sense because we know the produced modules are never loadable
- Remove unused 'AS' variable
[Kconfig]
- sanitize DEFCONFIG_LIST, and remove ARCH_DEFCONFIG from Kconfig files
- relax the 'imply' behavior so that symbols implied by y can become m
- make 'imply' obey 'depends on' in order to make 'imply' really weak
[Misc]
- add documentation on building the kernel with Clang/LLVM
- revive __HAVE_ARCH_STRLEN for 32bit sparc to use optimized strlen()
- fix warning from deb-pkg builds when CONFIG_DEBUG_INFO=n
- various script and Makefile cleanups

Merge tag 'selinux-pr-20200330' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux
Pull SELinux updates from Paul Moore:
"We've got twenty SELinux patches for the v5.7 merge window, the
highlights are below:
- Deprecate setting /sys/fs/selinux/checkreqprot to 1.
This flag was originally created to deal with legacy userspace and
the READ_IMPLIES_EXEC personality flag. We changed the default from
1 to 0 back in Linux v4.4 and now we are taking the next step of
deprecating it, at some point in the future we will take the final
step of rejecting 1.
- Allow kernfs symlinks to inherit the SELinux label of the parent
directory. In order to preserve backwards compatibility this is
protected by the genfs_seclabel_symlinks SELinux policy capability.
- Optimize how we store filename transitions in the kernel, resulting
in some significant improvements to policy load times.
- Do a better job calculating our internal hash table sizes which
resulted in additional policy load improvements and likely general
SELinux performance improvements as well.
- Remove the unused initial SIDs (labels) and improve how we handle
initial SIDs.
- Enable per-file labeling for the bpf filesystem.
- Ensure that we properly label NFS v4.2 filesystems to avoid a
temporary unlabeled condition.
- Add some missing XFS quota command types to the SELinux quota
access controls.
- Fix a problem where we were not updating the seq_file position
index correctly in selinuxfs.
- We consolidate some duplicated code into helper functions.
- A number of list to array conversions.
- Update Stephen Smalley's email address in MAINTAINERS"

dt-bindings: iio: Fix adi, ltc2983 uint64-matrix schema constraints
'minItems' and 'maxItems' apply at the same level as 'items' schemas as
the keywords apply to arrays. What's currently defined is a 3
dimensional matrix with the outer size being undefined. To fix this,
minItems/maxItems needs to be moved up a level.
With this fixed, the example fails validation. For matrix types, the dts
syntax must use brackets (<>) matching the schema definition. In this
case, the inner array size is 2 elements, so let's add the correct
bracketing.
