Pull more power management updates from Rafael Wysocki:
"These update the CPPC cpufreq driver and intel_pstate (which involves
updating the cpufreq core and the schedutil governor) and make
janitorial changes in the ACPI code handling processor objects.
Specifics:
- Rework the passive-mode "fast switch" path in the intel_pstate
driver to allow it receive the minimum (required) and target
(desired) performance information from the schedutil governor so as
to avoid running some workloads too fast (Rafael Wysocki).
- Make the intel_pstate driver allow the policy max limit to be
increased after the guaranteed performance value for the given CPU
has increased (Rafael Wysocki).
- Clean up the handling of CPU coordination types in the CPPC cpufreq
driver and make it export frequency domains information to user
space via sysfs (Ionela Voinescu).
- Fix the ACPI code handling processor objects to use a correct
coordination type when it fails to map frequency domains and drop a
redundant CPU map initialization from it (Ionela Voinescu, Punit
Agrawal)"

Merge KASAN updates from Andrew Morton.
This adds a new hardware tag-based mode to KASAN. The new mode is
similar to the existing software tag-based KASAN, but relies on arm64

(instead of shadow memory and compiler instrumentation).

This is a preparatory commit for the upcoming addition of a new hardware
tag-based (MTE-based) KASAN mode.
The new mode won't be using shadow memory, but will still use the concept
of memory granules. Each memory granule maps to a single metadata entry:
8 bytes per one shadow byte for generic mode, 16 bytes per one shadow byte
for software tag-based mode, and 16 bytes per one allocation tag for
hardware tag-based mode.
Rename KASAN_SHADOW_SCALE_SIZE to KASAN_GRANULE_SIZE, and
KASAN_SHADOW_MASK to KASAN_GRANULE_MASK.
Also use MASK when used as a mask, otherwise use SIZE.
No functional changes.

Pull clk updates from Stephen Boyd:
"The core framework got some nice improvements this time around. We
gained the ability to get struct clk pointers from a struct clk_hw so
that clk providers can consume the clks they provide, if they need to
do something like that. This has been a long missing part of the clk
provider API that will help us move away from exposing a struct clk
pointer in the struct clk_hw. Tracepoints are added for the
clk_set_rate() "range" functions, similar to the tracepoints we
already have for clk_set_rate() and we added a column to debugfs to
help developers understand the hardware enable state of clks in case
firmware or bootloader state is different than what is expected.
Overall the core changes are mostly improving the clk driver writing
experience.
At the driver level, we have the usual collection of driver updates
and new drivers for new SoCs. This time around the Qualcomm folks
introduced a good handful of clk drivers for various parts of three or
four SoCs. The SiFive folks added a new clk driver for their FU740
SoCs, coming in second on the diffstat and then Atmel AT91 and Amlogic
SoCs had lots of work done after that for various new features. One
last thing to note in the driver area is that the i.MX driver has
gained a new binding to support SCU clks after being on the list for
many months. It uses a two cell binding which is sort of rare in clk
DT bindings. Beyond that we have the usual set of driver fixes and
tweaks that come from more testing and finding out that some
configuration was wrong or that a driver could support being built as
a module.
Summary:
Core:
- Add some trace points for clk_set_rate() "range" functions
- Add hardware enable information to clk_summary debugfs
- Replace clk-provider.h with of_clk.h when possible
- Add devm variant of clk_notifier_register()
- Add clk_hw_get_clk() to generate a struct clk from a struct clk_hw
New Drivers:
- Bindings for Canaan K210 SoC clks
- Support for SiFive FU740 PRCI
- Camera clks on Qualcomm SC7180 SoCs
- GCC and RPMh clks on Qualcomm SDX55 SoCs
- RPMh clks on Qualcomm SM8350 SoCs
- LPASS clks on Qualcomm SM8250 SoCs

- DVFS support for AT91 clk driver
- Update git repo branch for Renesas clock drivers
- Add camera (CSI) and video-in (VIN) clocks on Renesas R-Car V3U
- Add RPC (QSPI/HyperFLASH) clocks on Renesas RZ/G2M, RZ/G2N, and RZ/G2E
- Stop using __raw_*() I/O accessors in Renesas clk drivers
- One more conversion of DT bindings to json-schema
- Make i.MX clk-gate2 driver more flexible
- New two cell binding for i.MX SCU clks
- Drop of_match_ptr() in i.MX8 clk drivers

The difference between extra-y and always-y is obscure.
Basically, Kbuild builds targets listed in extra-y and always-y in
visited Makefiles without relying on any dependency.
The difference is that extra-y is used to list the targets needed for
vmlinux whereas always-y is used to list the targets that must be always
built irrespective of final targets.
Kbuild skips extra-y when it is building only modules (i.e.
'make modules'). This is the long-standing behavior since extra-y was
introduced in 2003, and it is explained in that commit log [1].
For clarification, this is the extra-y vs always-y table:
extra-y always-y
'make' y y
'make vmlinux' y y
'make modules' n y
Kbuild skips extra-y also when building external modules since obviously
it never builds vmlinux.
Unfortunately, extra-y is wrongly used in many places of upstream code,
and even in external modules.
Using extra-y in external module Makefiles is wrong. What you should
use is probably always-y or 'targets'.
The current documentation for extra-y is misleading. I rewrote it, and
moved it to the section 3.7.
always-y is not documented anywhere. I added.

The if_changed macro is currently explained in the section
"Commands useful for building a boot image", but the use of
if_changed is not limited to the boot image.
It is often used together with custom rules. Let's split it as a
separate section, and insert it after the "Custom Rules" section.
I slightly reworded the explanation, re-numbered to fill the <deleted>

The two sections "3.10 Special Rules" and "7.8 Custom kbuild commands"
are related because you must understand both of them when you write
custom rules.
Actually I do not understand the policy about what to go into
"3 The kbuild files" and what into "7 Architecture Makefile".
This commit reworks the custom rule explanation as follows:
- Merged "7.8 Custom kbuild commands" into "3.10 Special Rules".
- Reword "Special Rules" to "Custom Rules" for consistency.
- Update the example for kecho because the blackfin Makefile
does not exist any more.
- Replace the example for cmd_<command> with a simpler one.

Precisely speaking, the arch directory is specified by $(SRCARCH),
not $(ARCH).
In old days, $(ARCH) actually matched to the arch directory because
32-bit and 64-bit were supported as separate architectures.
Most architectures (except arm/arm64) were unified like follows:
arch/i386, arch/x86_64 -> arch/x86
arch/sh, arch/sh64 -> arch/sh
arch/sparc, arch/sparc64 -> arch/sparc
To not break the user interface, commit 6752ed90da03 ("Kbuild: allow
arch/xxx to use a different source path") introduced SRCARCH to point
to the arch directory, still allowing to pass in the former ARCH=i386
or ARCH=x86_64.
Update the documents for preciseness, and add the explanation of SRCARCH.

Some RTCs, e.g. the pcf2127, can be used as a hardware watchdog. But
if the reset pin is not actually wired up, the driver exposes a
watchdog device that doesn't actually work.
Provide a standard binding that can be used to indicate that a given
RTC can perform a reset of the machine, similar to wakeup-source.

Pull RISC-V updates from Palmer Dabbelt:
"We have a handful of new kernel features for 5.11:
- Support for the contiguous memory allocator.
- Support for IRQ Time Accounting
- Support for stack tracing
- Support for strict /dev/mem
- Support for kernel section protection
I'm being a bit conservative on the cutoff for this round due to the
timing, so this is all the new development I'm going to take for this
cycle (even if some of it probably normally would have been OK). There
are, however, some fixes on the list that I will likely be sending
along either later this week or early next week.
There is one issue in here: one of my test configurations
(PREEMPT{,_DEBUG}=y) fails to boot on QEMU 5.0.0 (from April) as of
the .text.init alignment patch.
With any luck we'll sort out the issue, but given how many bugs get
fixed all over the place and how unrelated those features seem my
guess is that we're just running into something that's been lurking
for a while and has already been fixed in the newer QEMU (though I
wouldn't be surprised if it's one of these implicit assumptions we
have in the boot flow). If it was hardware I'd be strongly inclined to
look more closely, but given that users can upgrade their simulators
I'm less worried about it"

Pull GPIO updates from Linus Walleij:
"This is the bulk of the GPIO changes for the v5.11 kernel cycle:
Core changes:
- Retired the old set-up function for GPIO IRQ chips. All chips now
use the template struct gpio_irq_chip and pass that to the core to
be set up alongside the gpio_chip. We can finally get rid of the
old cruft.
- Some refactoring and clean up of the core code.
- Support edge event timestamps to be stamped using REALTIME (wall
clock) timestamps. We have found solid use cases for this, so we
support it.
New drivers:
- MStar MSC313 GPIO driver.
- HiSilicon GPIO driver.
Driver improvements:
- The PCA953x driver now also supports the NXP PCAL9554B/C chips.
- The mockup driver can now be probed from the device tree which is
pretty useful for virtual prototyping of devices.
- The Rcar driver now supports .get_multiple()
- The MXC driver dropped some legacy and became a pure device tree
client.
- The Exar driver was moved over to the IDA interface for

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
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 overlayfs updates from Miklos Szeredi:
- 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.
- Bug fixes as well as documentation updates.

Pull f2fs updates from Jaegeuk Kim:
"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
- fix nat entry count calculation in shrinker
- fix some stat information
And, we've refactored some logics and fix minor bugs as well"
