cpufreq: CPPC: Add support for frequency invariance
The Frequency Invariance Engine (FIE) is providing a frequency scaling correction factor that helps achieve more accurate load-tracking. Normally, this scaling factor can be obtained directly with the help of the cpufreq drivers as they know the exact frequency the hardware is running at. But that isn't the case for CPPC cpufreq driver. Another way of obtaining that is using the arch specific counter support, which is already present in kernel, but that hardware is optional for platforms. This patch updates the CPPC driver to register itself with the topology core to provide its own implementation (cppc_scale_freq_tick()) of topology_scale_freq_tick() which gets called by the scheduler on every tick. Note that the arch specific counters have higher priority than CPPC counters, if available, though the CPPC driver doesn't need to have any special handling for that. On an invocation of cppc_scale_freq_tick(), we schedule an irq work (since we reach here from hard-irq context), which then schedules a normal work item and cppc_scale_freq_workfn() updates the per_cpu arch_freq_scale variable based on the counter updates since the last tick. To allow platforms to disable this CPPC counter-based frequency invariance support, this is all done under CONFIG_ACPI_CPPC_CPUFREQ_FIE, which is enabled by default. This also exports sched_setattr_nocheck() as the CPPC driver can be built as a module.

Pull timer updates from Thomas Gleixner:
"Time and clocksource/clockevent related updates:
Core changes:
- Infrastructure to support per CPU "broadcast" devices for per CPU
clockevent devices which stop in deep idle states. This allows us
to utilize the more efficient architected timer on certain ARM SoCs
for normal operation instead of permanentely using the slow to
access SoC specific clockevent device.
- Print the name of the broadcast/wakeup device in /proc/timer_list
- Make the clocksource watchdog more robust against delays between
reading the current active clocksource and the watchdog
clocksource. Such delays can be caused by NMIs, SMIs and vCPU
preemption.
Handle this by reading the watchdog clocksource twice, i.e. before
and after reading the current active clocksource. In case that the
two watchdog reads shows an excessive time delta, the read sequence
is repeated up to 3 times.
- Improve the debug output and add a test module for the watchdog
mechanism.
- Reimplementation of the venerable time64_to_tm() function with a
faster and significantly smaller version. Straight from the source,
i.e. the author of the related research paper contributed this!
Driver changes:
- No new drivers, not even new device tree bindings!
- Fixes, improvements and cleanups and all over the place"

Updates for the interrupt subsystem:
Core changes:
- Cleanup and simplification of common code to invoke the low level
interrupt flow handlers when this invocation requires irqdomain
resolution. Add the necessary core infrastructure.
- Provide a proper interface for modular PMU drivers to set the
interrupt affinity.
- Add a request flag which allows to exclude interrupts from spurious
interrupt detection. Useful especially for IPI handlers which always
return IRQ_HANDLED which turns the spurious interrupt detection into a
pointless waste of CPU cycles.
Driver changes:
- Bulk convert interrupt chip drivers to the new irqdomain low level flow
handler invocation mechanism.
- Add device tree bindings for the Renesas R-Car M3-W+ SoC
- Enable modular build of the Qualcomm PDC driver
- The usual small fixes and improvements.

This was a reasonably active cycle for documentation; this pull includes:
- Some kernel-doc cleanups. That script is still regex onslaught from
hell, but it has gotten a little better.
- Improvements to the checkpatch docs, which are also used by the tool
itself.
- A major update to the pathname lookup documentation.
- Elimination of :doc: markup, since our automarkup magic can create
references from filenames without all the extra noise.
- The flurry of Chinese translation activity continues.
Plus, of course, the usual collection of updates, typo fixes, and warning
fixes.

Pull btrfs updates from David Sterba:
"A normal mix of improvements, core changes and features that user have
been missing or complaining about.
User visible changes:
- new sysfs exports:
- add sysfs knob to limit scrub IO bandwidth per device
- device stats are also available in
/sys/fs/btrfs/FSID/devinfo/DEVID/error_stats
- support cancellable resize and device delete ioctls
- change how the empty value is interpreted when setting a property,
so far we have only 'btrfs.compression' and we need to distinguish
a reset to defaults and setting "do not compress", in general the
empty value will always mean 'reset to defaults' for any other
property, for compression it's either 'no' or 'none' to forbid
compression
Performance improvements:
- no need for full sync when truncation does not touch extents,
reported run time change is -12%
- avoid unnecessary logging of xattrs during fast fsyncs (+17%
throughput, -17% runtime on xattr stress workload)
Core:
- preemptive flushing improvements and fixes
- adjust clamping logic on multi-threaded workloads to avoid
flushing too soon
- take into account global block reserve, may help on almost full
filesystems
- continue flushing when there are enough pending delalloc and
ordered bytes
- simplify logic around conditional transaction commit, a workaround
used in the past for throttling that's been superseded by ticket
reservations that manage the throttling in a better way
- subpage blocksize preparation:
- submit read time repair only for each corrupted sector
- scrub repair now works with sectors and not pages
- free space cache (v1) works with sectors and not pages
- more fine grained bio tracking for extents
- subpage support in page callbacks, extent callbacks, end io
callbacks
- simplify transaction abort logic and always abort and don't check
various potentially unreliable stats tracked by the transaction
- exclusive operations can do more checks when started and allow eg.
cancellation of the same running operation
- ensure relocation never runs while we have send operations running,
e.g. when zoned background auto reclaim starts
Fixes:
- zoned: more sanity checks of write pointer
- improve error handling in delayed inodes
- send:
- fix invalid path for unlink operations after parent
orphanization
- fix crash when memory allocations trigger reclaim
- skip compression of we have only one page (can't make things
better)
- empty value of a property newly means reset to default
Other:
- lots of cleanups, comment updates, yearly typo fixing
- disable build on platforms having page size 256K"

"There's a reasonable amount here and the juicy details are all below.
It's worth noting that the MTE/KASAN changes strayed outside of our

rather that take them via the -mm tree.

seccomp: Support atomic "addfd + send reply"
Alban Crequy reported a race condition userspace faces when we want to add some fds and make the syscall return them[1] using seccomp notify. The problem is that currently two different ioctl() calls are needed by the process handling the syscalls (agent) for another userspace process (target): SECCOMP_IOCTL_NOTIF_ADDFD to allocate the fd and SECCOMP_IOCTL_NOTIF_SEND to return that value. Therefore, it is possible for the agent to do the first ioctl to add a file descriptor but the target is interrupted (EINTR) before the agent does the second ioctl() call. This patch adds a flag to the ADDFD ioctl() so it adds the fd and returns that value atomically to the target program, as suggested by Kees Cook[2]. This is done by simply allowing seccomp_do_user_notification() to add the fd and return it in this case. Therefore, in this case the target wakes up from the wait in seccomp_do_user_notification() either to interrupt the syscall or to add the fd and return it. This "allocate an fd and return" functionality is useful for syscalls that return a file descriptor only, like connect(2). Other syscalls that return a file descriptor but not as return value (or return more than one fd), like socketpair(), pipe(), recvmsg with SCM_RIGHTs, will not work with this flag. This effectively combines SECCOMP_IOCTL_NOTIF_ADDFD and SECCOMP_IOCTL_NOTIF_SEND into an atomic opteration. The notification's return value, nor error can be set by the user. Upon successful invocation of the SECCOMP_IOCTL_NOTIF_ADDFD ioctl with the SECCOMP_ADDFD_FLAG_SEND flag, the notifying process's errno will be 0, and the return value will be the file descriptor number that was installed.

Scheduler udpates for this cycle:
- Changes to core scheduling facilities:
- Add "Core Scheduling" via CONFIG_SCHED_CORE=y, which enables
coordinated scheduling across SMT siblings. This is a much
requested feature for cloud computing platforms, to allow
the flexible utilization of SMT siblings, without exposing
untrusted domains to information leaks & side channels, plus
to ensure more deterministic computing performance on SMT
systems used by heterogenous workloads.
There's new prctls to set core scheduling groups, which
allows more flexible management of workloads that can share
siblings.
- Fix task->state access anti-patterns that may result in missed
wakeups and rename it to ->__state in the process to catch new
abuses.
- Load-balancing changes:
- Tweak newidle_balance for fair-sched, to improve
'memcache'-like workloads.
- "Age" (decay) average idle time, to better track & improve workloads
such as 'tbench'.
- Fix & improve energy-aware (EAS) balancing logic & metrics.
- Fix & improve the uclamp metrics.
- Fix task migration (taskset) corner case on !CONFIG_CPUSET.
- Fix RT and deadline utilization tracking across policy changes
- Introduce a "burstable" CFS controller via cgroups, which allows
bursty CPU-bound workloads to borrow a bit against their future
quota to improve overall latencies & batching. Can be tweaked
via /sys/fs/cgroup/cpu/<X>/cpu.cfs_burst_us.
- Rework assymetric topology/capacity detection & handling.
- Scheduler statistics & tooling:
- Disable delayacct by default, but add a sysctl to enable
it at runtime if tooling needs it. Use static keys and
other optimizations to make it more palatable.
- Use sched_clock() in delayacct, instead of ktime_get_ns().
- Misc cleanups and fixes.

Locking changes for this cycle:
- Core locking & atomics:
- Convert all architectures to ARCH_ATOMIC: move every
architecture to ARCH_ATOMIC, then get rid of ARCH_ATOMIC
and all the transitory facilities and #ifdefs.
Much reduction in complexity from that series:
63 files changed, 756 insertions(+), 4094 deletions(-)
- Self-test enhancements
- Futexes:
- Add the new FUTEX_LOCK_PI2 ABI, which is a variant that
doesn't set FLAGS_CLOCKRT (.e. uses CLOCK_MONOTONIC).
[ The temptation to repurpose FUTEX_LOCK_PI's implicit
setting of FLAGS_CLOCKRT & invert the flag's meaning
to avoid having to introduce a new variant was
resisted successfully. ]
- Enhance futex self-tests
- Lockdep:
- Fix dependency path printouts
- Optimize trace saving
- Broaden & fix wait-context checks

Pull locking updates from Ingo Molnar:
- Core locking & atomics:
- Convert all architectures to ARCH_ATOMIC: move every architecture
to ARCH_ATOMIC, then get rid of ARCH_ATOMIC and all the
transitory facilities and #ifdefs.
Much reduction in complexity from that series:
63 files changed, 756 insertions(+), 4094 deletions(-)
- Self-test enhancements
- Futexes:
- Add the new FUTEX_LOCK_PI2 ABI, which is a variant that doesn't
set FLAGS_CLOCKRT (.e. uses CLOCK_MONOTONIC).
[ The temptation to repurpose FUTEX_LOCK_PI's implicit setting of
FLAGS_CLOCKRT & invert the flag's meaning to avoid having to
introduce a new variant was resisted successfully. ]
- Enhance futex self-tests
- Lockdep:
- Fix dependency path printouts
- Optimize trace saving
- Broaden & fix wait-context checks
- Misc cleanups and fixes.

spi: Updates for v5.14
The biggest single thing in the diffstat here is a massive overhaul of
the PXA2xx driver from Andy Shevchenko (the IP is still in use on modern
Intel systems), though we also have quite a lot of core work as well:
- Better support for mixing native and GPIO chip selects also from
Andy.
- Support for devices with multiple chip selects from Sebastian
Reichel.
- Helper for polling status registers in spi-mem from Patrice Chotard.
- Support for Renesas RZ/N1 and Rockchip RV1126.

regulator: Updates for v5.14
The main core change this release is generic support for handling of
hardware errors from Matti Vaittinen, including some small updates to
the reboot and thermal code so we can share support for powering off the
system if things are going wrong enough. Otherwise this release we've
mainly seen the addition of new drivers, including MT6359 which has
pulled in some small changes from the MFD tree for build dependencies.
- Support for controlling the trigger points for hardware error
detection, and shared handlers for this.
- Support for Maxim MAX8993, Mediatek MT6359 and MT6359P, Qualcomm
PM8226 and SA8115P-ADP, and Sylergy TCS4526.

Pull libata updates from Jens Axboe:
"The big change in this round is that we're finally in a position where
we can sanely remove the old drivers/ide/ code, as libata covers
everything we need by now.
This is exciting for two reasons:
1) we delete a lot of legacy code that doesn't really meet the
standards we have today, and
2) it enables us to clean up various bits in the block layer that
exist only because of the old IDE code.
Outside of that, just a few minor fixes here, fixups for warnings,
etc"

kvm: x86: Allow userspace to handle emulation errors
Add a fallback mechanism to the in-kernel instruction emulator that allows userspace the opportunity to process an instruction the emulator was unable to. When the in-kernel instruction emulator fails to process an instruction it will either inject a #UD into the guest or exit to userspace with exit reason KVM_INTERNAL_ERROR. This is because it does not know how to proceed in an appropriate manner. This feature lets userspace get involved to see if it can figure out a better path forward.
