Pull tracing updates from Steven Rostedt:
"The major update to this release is that there's a new arch config
option called CONFIG_HAVE_DYNAMIC_FTRACE_WITH_ARGS.
Currently, only x86_64 enables it. All the ftrace callbacks now take a
struct ftrace_regs instead of a struct pt_regs. If the architecture
has HAVE_DYNAMIC_FTRACE_WITH_ARGS enabled, then the ftrace_regs will
have enough information to read the arguments of the function being
traced, as well as access to the stack pointer.
This way, if a user (like live kernel patching) only cares about the
arguments, then it can avoid using the heavier weight "regs" callback,
that puts in enough information in the struct ftrace_regs to simulate
a breakpoint exception (needed for kprobes).
A new config option that audits the timestamps of the ftrace ring
buffer at most every event recorded.
Ftrace recursion protection has been cleaned up to move the protection
to the callback itself (this saves on an extra function call for those
callbacks).
Perf now handles its own RCU protection and does not depend on ftrace
to do it for it (saving on that extra function call).
New debug option to add "recursed_functions" file to tracefs that
lists all the places that triggered the recursion protection of the
function tracer. This will show where things need to be fixed as
recursion slows down the function tracer.
The eval enum mapping updates done at boot up are now offloaded to a
work queue, as it caused a noticeable pause on slow embedded boards.
Various clean ups and last minute fixes"

Pull modules updates from Jessica Yu:
"Summary of modules changes for the 5.11 merge window:
- Fix a race condition between systemd/udev and the module loader.
The module loader was sending a uevent before the module was fully
initialized (i.e., before its init function has been called). This
means udev can start processing the module uevent before the module
has finished initializing, and some udev rules expect that the
module has initialized already upon receiving the uevent.
This resulted in some systemd mount units failing if udev processes
the event faster than the module can finish init. This is fixed by
delaying the uevent until after the module has called its init
routine.
- Make the linker array sections for kernel params and module version
attributes more robust by switching to use the alignment of the
type in question.
Namely, linker section arrays will be constructed using the
alignment required by the struct (using __alignof__()) as opposed
to a specific value such as sizeof(void *) or sizeof(long). This is
less likely to cause breakages should the size of the type ever
change (Johan Hovold)
- Fix module state inconsistency by setting it back to GOING when a
module fails to load and is on its way out (Miroslav Benes)

- Allow unprivileged mounting in a user namespace.
For quite some time the security model of overlayfs has been that
operations on underlying layers shall be performed with the
privileges of the mounting task.
This way an unprvileged user cannot gain privileges by the act of
mounting an overlayfs instance. A full audit of all function calls
made by the overlayfs code has been performed to see whether they
conform to this model, and this branch contains some fixes in this
regard.
- Support running on copied filesystem images by optionally disabling
UUID verification.

"In this round, we've made more work into per-file compression support.
For example, F2FS_IOC_GET | SET_COMPRESS_OPTION provides a way to
change the algorithm or cluster size per file. F2FS_IOC_COMPRESS |
DECOMPRESS_FILE provides a way to compress and decompress the existing
normal files manually.
There is also a new mount option, compress_mode=fs|user, which can
control who compresses the data.
Chao also added a checksum feature with a mount option so that
we are able to detect any corrupted cluster.
In addition, Daniel contributed casefolding with encryption patch,
which will be used for Android devices.
Summary:
Enhancements:
- add ioctls and mount option to manage per-file compression feature
- support casefolding with encryption
- support checksum for compressed cluster
- avoid IO starvation by replacing mutex with rwsem
- add sysfs, max_io_bytes, to control max bio size
Bug fixes:
- fix use-after-free issue when compression and fsverity are enabled
- fix consistency corruption during fault injection test
- fix data offset for lseek
- get rid of buffer_head which has 32bits limit in fiemap
- fix some bugs in multi-partitions support

drm/edid: fix objtool warning in drm_cvt_modes()
Commit
991fcb77f490 ("drm/edid: Fix uninitialized variable in
drm_cvt_modes()") just replaced one warning with another.
The original warning about a possibly uninitialized variable was due to
the compiler not being smart enough to see that the case statement
actually enumerated all possible cases. And the initial fix was just to
add a "default" case that had a single "unreachable()", just to tell the
compiler that that situation cannot happen.
However, that doesn't actually fix the fundamental reason for the
problem: the compiler still doesn't see that the existing case
statements enumerate all possibilities, so the compiler will still
generate code to jump to that unreachable case statement. It just won't
complain about an uninitialized variable any more.
So now the compiler generates code to our inline asm marker that we told
it would not fall through, and end end result is basically random. We
have created a bridge to nowhere.
And then, depending on the random details of just exactly what the
compiler ends up doing, 'objtool' might end up complaining about the
conditional branches (for conditions that cannot happen, and that thus
will never be taken - but if the compiler was not smart enough to figure
that out, we can't expect objtool to do so) going off in the weeds.
So depending on how the compiler has laid out the result, you might see
something like this:
drivers/gpu/drm/drm_edid.o: warning: objtool: do_cvt_mode() falls through to next function drm_mode_detailed.isra.0()
and now you have a truly inscrutable warning that makes no sense at all
unless you start looking at whatever random code the compiler happened
to generate for our bare "unreachable()" statement.
IOW, don't use "unreachable()" unless you have an _active_ operation
that generates code that actually makes it obvious that something is not
reachable (ie an UD instruction or similar).
Solve the "compiler isn't smart enough" problem by just marking one of
the cases as "default", so that even when the compiler doesn't otherwise
see that we've enumerated all cases, the compiler will feel happy and
safe about there always being a valid case that initializes the 'width'
variable.
This also generates better code, since now the compiler doesn't generate
comparisons for five different possibilities (the four real ones and the
one that can't happen), but just for the three real ones and "the rest"
(which is that last one).
A smart enough compiler that sees that we cover all the cases won't care.

Pull ARM SoC driver updates from Arnd Bergmann:
"There are a couple of subsystems maintained by other people that merge
their drivers through the SoC tree, those changes include:
- The SCMI firmware framework gains support for sensor notifications
and for controlling voltage domains.
- A large update for the Tegra memory controller driver, integrating
it better with the interconnect framework
- The memory controller subsystem gains support for Mediatek MT8192
- The reset controller framework gains support for sharing pulsed
resets
For Soc specific drivers in drivers/soc, the main changes are
- The Allwinner/sunxi MBUS gets a rework for the way it handles
dma_map_ops and offsets between physical and dma address spaces.
- An errata fix plus some cleanups for Freescale Layerscape SoCs
- A cleanup for renesas drivers regarding MMIO accesses.
- New SoC specific drivers for Mediatek MT8192 and MT8183 power
domains
- New SoC specific drivers for Aspeed AST2600 LPC bus control and SoC
identification.
- Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660 and
SDX55.
- A rework of the TI AM33xx 'genpd' power domain support to use
information from DT instead of platform data
- Support for TI AM64x SoCs
- Allow building some Amlogic drivers as modules instead of built-in
Finally, there are numerous cleanups and smaller bug fixes for
Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips,
Renesas, and Xilinx SoCs"

"Across all platforms, there is a continued move towards DT schema for
validating the dts files. As a result there are bug fixes for mistakes
that are found using these schema, in addition to warnings from the
dtc compiler.
As usual, many changes are for adding support for additional on-chip
and on-board components in the machines we already support.
The newly supported SoCs for this release are:
- MStar Infinity2M, a low-end IP camera chip based on a dual-core
Cortex-A7, otherwise similar to the Infinity chip we already
support. This is also known as the SigmaStar SSD202D, and we add
support for the Honestar ssd201htv2 development kit.
- Nuvoton NPCM730, a Cortex-A9 based Baseboard Management Controller
(BMC), in the same family as the NPCM750. This gets used in the
Ampere Altra based "Fii Kudo" server and the Quanta GSJ, both of
which are added as well.
- Broadcom BCM4908, a 64-bit home router chip based on Broadcom's own
Brahma-B53 CPU. Support is also added for the Asus ROG Rapture
GT-AC5300 high-end WiFi router based on this chip.
- Mediatek MT8192 is a new SoC based on eight Cortex-A76/A55 cores,
meant for faster Chromebooks and tablets. It gets added along with
its reference design.
- Mediatek MT6779 (Helio P90) is a high-end phone chip from last
year's generation, also added along with its reference board. This
one is still based on Cortex-A75/A55.
- Mediatek MT8167 is a version of the already supported MT8516 chip,
both based on Cortex-A35. It gets added along with the "Pumpkin"
single board computer, but is likely to also make its way into
low-end tablets in the future.
For the already supported chips, there are a number of new boards.
Interestingly there are more 32-bit machines added this time than
64-bit. Here is a brief list of the new boards:
- Three new Mikrotik router variants based on Marvell Prestera
98DX3236, a close relative of the more common Armada XP
- A reference board for the Marvell Armada 382
- Three new servers using ASpeed baseboard management controllers,
the actual machines being from Bytedance, Facebook and IBM, and one
machine using the Nuvoton NPCM750 BMC.
- The Galaxy Note 10.1 (P4) tablet, using an Exynos 4412.
- The usual set of 32-bit i.MX industrial/embedded hardware:
* Protonic WD3 (tractor e-cockpit)
* Kamstrup OMNIA Flex Concentrator (smart grid platform)
* Van der Laan LANMCU (food storage)
* Altesco I6P (vehicle inspection stations)
* PHYTEC phyBOARD-Segin/phyCORE-i.MX6UL baseboard
- DH electronics STM32MP157C DHCOM, a PicoITX carrier board for the
aleady supported DHCOM module
- Three new Allwinner SoC based single-board computers:
* NanoPi R1 (H3 based)
* FriendlyArm ZeroPi (H3 based)
* Elimo Initium SBC (S3 based)
- Ouya Game Console based on Nvidia Tegra 3
- Version 5 of the already supported Zynq Z-Turn MYIR Board
- LX2162AQDS, a reference platform for NXP Layerscape LX2162A, which
is a repackaged 16-core LX2160A
- A series of Kontron i.MX8M Mini baseboard/SoM versions
- Espressobin Ultra, a new variant of the popular Armada 3700 based
board,
- IEI Puzzle-M801, a rackmount network appliance based on Marvell
Armada 8040
- Microsoft Lumia 950 XL, a phone
- HDK855 and HDK865 Hardware development kits for Qualcomm sm8250 and
sm8150, respectively
- Three new board variants of the "Trogdor" Chromebook (sc7180)
- New board variants of the Renesas based "Kingfisher" and "HiHope"
reference boards
- Kobol Helios64, an open source NAS appliance based on Rockchips
RK3399
- Engicam PX30.Core, a SoM based on Rockchip PX30, along with a few
carrier boards"

devlink: use _BITUL() macro instead of BIT() in the UAPI header
The BIT() macro is not available for the UAPI headers. Moreover, it can
be defined differently in user space headers. Thus, replace its usage

"This is the bulk of pin control changes for the v5.11 kernel.
Drivers, drivers and drivers. Not a single core change.
Some new stuff, especially a bunch of new Intel, Qualcomm and Ocelot
SoCs.
As part of the modularization attempt, I applied one patch affecting
the firmware subsystem as a functional (not syntactic/semantic)
dependency and then it blew up in our face, so I had to revert it,
bummer. It will come in later, through that subsystem, I guess.
New drivers:
- New driver for the Microchip Serial GPIO "SGPIO".
- Qualcomm SM8250 LPASS (Low Power Audio Subsystem) GPIO driver.
New subdrivers:
- Intel Lakefield subdriver.
- Intel Elkhart Lake subdriver.
- Intel Alder Lake-S subdriver.
- Qualcomm MSM8953 subdriver.
- Qualcomm SDX55 subdriver.
- Qualcomm SDX55 PMIC subdriver.
- Ocelot Luton SoC subdriver.
- Ocelot Serval SoC subdriver.
Modularization:
- The Meson driver can now be built as modules.
- The Qualcomm driver(s) can now be built as modules.
Incremental improvements:
- The Intel driver now supports pin configuration for GPIO-related
configurations.
- A bunch of Renesas PFC drivers have been augmented with support for
QSPI pins, groups and functions.
- Non-critical fixes to the irq handling in the Allwinner Sunxi

arm64: make _TIF_WORK_MASK bits contiguous

Pull TIF_NOTIFY_SIGNAL updates from Jens Axboe:
"This sits on top of of the core entry/exit and x86 entry branch from
the tip tree, which contains the generic and x86 parts of this work.
Here we convert the rest of the archs to support TIF_NOTIFY_SIGNAL.
With that done, we can get rid of JOBCTL_TASK_WORK from task_work and
signal.c, and also remove a deadlock work-around in io_uring around
knowing that signal based task_work waking is invoked with the sighand
wait queue head lock.
The motivation for this work is to decouple signal notify based
task_work, of which io_uring is a heavy user of, from sighand. The
sighand lock becomes a huge contention point, particularly for
threaded workloads where it's shared between threads. Even outside of
threaded applications it's slower than it needs to be.
Roman Gershman <romger@amazon.com> reported that his networked
workload dropped from 1.6M QPS at 80% CPU to 1.0M QPS at 100% CPU
after io_uring was changed to use TIF_NOTIFY_SIGNAL. The time was all
spent hammering on the sighand lock, showing 57% of the CPU time there
[1].
There are further cleanups possible on top of this. One example is

1a000000!mdio!switch@10:02] driver [Qualcomm Atheros AR9331 built-in PHY] (irq=13)
DSA: tree 0 setup
To fix it, it is better to move access to MDIO register to the .irq_bus_sync_unlock
call back.

Pull audit updates from Paul Moore:
"A small set of audit patches for v5.11 with four patches in total and
only one of any real significance.
Richard's patch to trigger accompanying records causes the kernel to
emit additional related records when an audit event occurs; helping
provide some much needed context to events in the audit log. It is
also worth mentioning that this is a revised patch based on an earlier
attempt that had to be reverted in the v5.8 time frame.
Everything passes our test suite, and with no problems reported please
merge this for v5.11"
