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
- 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"

Merge tag 'netfs-fixes-20210621' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull netfs fixes from David Howells:
"This contains patches to fix netfs_write_begin() and afs_write_end()
in the following ways:
(1) In netfs_write_begin(), extract the decision about whether to skip
a page out to its own helper and have that clear around the region
to be written, but not clear that region. This requires the
filesystem to patch it up afterwards if the hole doesn't get
completely filled.
(2) Use offset_in_thp() in (1) rather than manually calculating the
offset into the page.
(3) Due to (1), afs_write_end() now needs to handle short data write
into the page by generic_perform_write(). I've adopted an
analogous approach to ceph of just returning 0 in this case and
letting the caller go round again.
It also adds a note that (in the future) the len parameter may extend
beyond the page allocated. This is because the page allocation is
deferred to write_begin() and that gets to decide what size of THP to
allocate."
Jeff Layton points out:
"The netfs fix in particular fixes a data corruption bug in cephfs"

mm/page_alloc: __alloc_pages_bulk(): do bounds check before accessing array
In the event that somebody would call this with an already fully
populated page_array, the last loop iteration would do an access beyond
the end of page_array.
It's of course extremely unlikely that would ever be done, but this
triggers my internal static analyzer. Also, if it really is not
supposed to be invoked this way (i.e., with no NULL entries in
page_array), the nr_populated<nr_pages check could simply be removed
instead.

mm/hwpoison: do not lock page again when me_huge_page() successfully recovers
Currently me_huge_page() temporary unlocks page to perform some actions
then locks it again later. My testcase (which calls hard-offline on
some tail page in a hugetlb, then accesses the address of the hugetlb
range) showed that page allocation code detects this page lock on buddy
page and printed out "BUG: Bad page state" message.
check_new_page_bad() does not consider a page with __PG_HWPOISON as bad
page, so this flag works as kind of filter, but this filtering doesn't
work in this case because the "bad page" is not the actual hwpoisoned
page. So stop locking page again. Actions to be taken depend on the
page type of the error, so page unlocking should be done in ->action()
callbacks. So let's make it assumed and change all existing callbacks
that way.

mm,hwpoison: return -EHWPOISON to denote that the page has already been poisoned
When memory_failure() is called with MF_ACTION_REQUIRED on the page that has already been hwpoisoned, memory_failure() could fail to send SIGBUS to the affected process, which results in infinite loop of MCEs. Currently memory_failure() returns 0 if it's called for already hwpoisoned page, then the caller, kill_me_maybe(), could return without sending SIGBUS to current process. An action required MCE is raised when the current process accesses to the broken memory, so no SIGBUS means that the current process continues to run and access to the error page again soon, so running into MCE loop. This issue can arise for example in the following scenarios: - Two or more threads access to the poisoned page concurrently. If local MCE is enabled, MCE handler independently handles the MCE events. So there's a race among MCE events, and the second or latter threads fall into the situation in question. - If there was a precedent memory error event and memory_failure() for the event failed to unmap the error page for some reason, the subsequent memory access to the error page triggers the MCE loop situation. To fix the issue, make memory_failure() return an error code when the error page has already been hwpoisoned. This allows memory error handler to control how it sends signals to userspace. And make sure that any process touching a hwpoisoned page should get a SIGBUS even in "already hwpoisoned" path of memory_failure() as is done in page fault path.

mm/memory-failure: use a mutex to avoid memory_failure() races
Patch series "mm,hwpoison: fix sending SIGBUS for Action Required MCE", v5. I wrote this patchset to materialize what I think is the current allowable solution mentioned by the previous discussion [1]. I simply borrowed Tony's mutex patch and Aili's return code patch, then I queued another one to find error virtual address in the best effort manner. I know that this is not a perfect solution, but should work for some typical case. [1]: https://lore.kernel.org/linux-mm/20210331192540.2141052f@alex-virtual-machine/ This patch (of 2): There can be races when multiple CPUs consume poison from the same page. The first into memory_failure() atomically sets the HWPoison page flag and begins hunting for tasks that map this page. Eventually it invalidates those mappings and may send a SIGBUS to the affected tasks. But while all that work is going on, other CPUs see a "success" return code from memory_failure() and so they believe the error has been handled and continue executing. Fix by wrapping most of the internal parts of memory_failure() in a mutex.

It is caused by the following race between kthread_mod_delayed_work()
and kthread_cancel_delayed_work_sync():

Context: Thread A Context: Thread B
kthread_mod_delayed_work()
spin_lock()

Context: IRQ
kthread_delayed_work_timer_fn()
spin_lock()
list_del_init(&work->node);
spin_unlock()
BANG: flush_work is not longer linked and will never get proceed.
The problem is that kthread_mod_delayed_work() checks work->canceling
flag before canceling the timer.
A simple solution is to (re)check work->canceling after
__kthread_cancel_work(). But then it is not clear what should be
returned when __kthread_cancel_work() removed the work from the queue
(list) and it can't queue it again with the new @delay.
The return value might be used for reference counting. The caller has
to know whether a new work has been queued or an existing one was
replaced.
The proper solution is that kthread_mod_delayed_work() will remove the
work from the queue (list) _only_ when work->canceling is not set. The
flag must be checked after the timer is stopped and the remaining
operations can be done under worker->lock.
Note that kthread_mod_delayed_work() could remove the timer and then
bail out. It is fine. The other canceling caller needs to cancel the
timer as well. The important thing is that the queue (list)
manipulation is done atomically under worker->lock.

KVM: s390: prepare for hugepage vmalloc
The Create Secure Configuration Ultravisor Call does not support using
large pages for the virtual memory area. This is a hardware limitation.
This patch replaces the vzalloc call with an almost equivalent call to
the newly introduced vmalloc_no_huge function, which guarantees that
only small pages will be used for the backing.
The new call will not clear the allocated memory, but that has never
been an actual requirement.
