      Pull io_uring updates from Jens Axboe:
      
       - Support for multi-shot mode for POLL requests
      
       - More efficient reference counting. This is shamelessly stolen from
         the mm side. Even though referencing is mostly single/dual user, the
         128 count was retained to keep the code the same. Maybe this
         should/could be made generic at some point.
      
       - Removal of the need to have a manager thread for each ring. The
         manager threads only job was checking and creating new io-threads as
         needed, instead we handle this from the queue path.
      
       - Allow SQPOLL without CAP_SYS_ADMIN or CAP_SYS_NICE. Since 5.12, this
         thread is "just" a regular application thread, so no need to restrict
         use of it anymore.
      
       - Cleanup of how internal async poll data lifetime is managed.
      
       - Fix for syzbot reported crash on SQPOLL cancelation.
      
       - Make buffer registration more like file registrations, which includes
         flexibility in avoiding full set unregistration and re-registration.
      
       - Fix for io-wq affinity setting.
      
       - Be a bit more defensive in task->pf_io_worker setup.
      
       - Various SQPOLL fixes.
      
       - Cleanup of SQPOLL creds handling.
      
       - Improvements to in-flight request tracking.

       - Clean up SCHED_DEBUG: move the decades old mess of sysctl, procfs and
         debugfs interfaces to a unified debugfs interface.
      
       - Signals: Allow caching one sigqueue object per task, to improve
         performance & latencies.
      
       - Improve newidle_balance() irq-off latencies on systems with a large
         number of CPU cgroups.

       - Improve the PELT metrics for certain workloads
      
       - Reintroduce select_idle_smt() to improve load-balancing locality -
         but without the previous regressions
      
       - Add 'scheduler latency debugging': warn after long periods of pending
         need_resched. This is an opt-in feature that requires the enabling of
         the LATENCY_WARN scheduler feature, or the use of the
         resched_latency_warn_ms=xx boot parameter.
      
       - CPU hotplug fixes for HP-rollback, and for the 'fail' interface. Fix
         remaining balance_push() vs. hotplug holes/races
      
       - PSI fixes, plus allow /proc/pressure/ files to be written by
         CAP_SYS_RESOURCE tasks as well
      
       - Fix/improve various load-balancing corner cases vs. capacity margins
      
       - Fix sched topology on systems with NUMA diameter of 3 or above
      
       - Fix PF_KTHREAD vs to_kthread() race

      Pull perf event updates from Ingo Molnar:
      
       - Improve Intel uncore PMU support:
      
           - Parse uncore 'discovery tables' - a new hardware capability
             enumeration method introduced on the latest Intel platforms. This
             table is in a well-defined PCI namespace location and is read via
             MMIO. It is organized in an rbtree.
      
             These uncore tables will allow the discovery of standard counter
             blocks, but fancier counters still need to be enumerated
             explicitly.
      
           - Add Alder Lake support
      
           - Improve IIO stacks to PMON mapping support on Skylake servers
      
       - Add Intel Alder Lake PMU support - which requires the introduction of
         'hybrid' CPUs and PMUs. Alder Lake is a mix of Golden Cove ('big')
         and Gracemont ('small' - Atom derived) cores.
      
         The CPU-side feature set is entirely symmetrical - but on the PMU
         side there's core type dependent PMU functionality.
      
       - Reduce data loss with CPU level hardware tracing on Intel PT / AUX
         profiling, by fixing the AUX allocation watermark logic.
      
       - Improve ring buffer allocation on NUMA systems
      
       - Put 'struct perf_event' into their separate kmem_cache pool
      
       - Add support for synchronous signals for select perf events. The
         immediate motivation is to support low-overhead sampling-based race
         detection for user-space code. The feature consists of the following
         main changes:
      
           - Add thread-only event inheritance via
             perf_event_attr::inherit_thread, which limits inheritance of
             events to CLONE_THREAD.
      
           - Add the ability for events to not leak through exec(), via
             perf_event_attr::remove_on_exec.
      
           - Allow the generation of SIGTRAP via perf_event_attr::sigtrap,
             extend siginfo with an u64 ::si_perf, and add the breakpoint
             information to ::si_addr and ::si_perf if the event is
             PERF_TYPE_BREAKPOINT.
      
         The siginfo support is adequate for breakpoints right now - but the
         new field can be used to introduce support for other types of
         metadata passed over siginfo as well.
      
       - Misc fixes, cleanups and smaller updates.

       - Stop synchronizing kernel log buffer readers by logbuf_lock. As a
         result, the access to the buffer is fully lockless now.
      
         Note that printk() itself still uses locks because it tries to flush
         the messages to the console immediately. Also the per-CPU temporary
         buffers are still there because they prevent infinite recursion and
         serialize backtraces from NMI. All this is going to change in the
         future.
      
       - kmsg_dump API rework and cleanup as a side effect of the logbuf_lock
         removal.

       - expose PCI device UID as index, including an indicator if the uid is
         unique.
      
       - remove some oprofile leftovers.
      
       - improve stack unwinder tests.
      
       - don't use gcc atomic builtins anymore, just like all other
         architectures. Even though I'm sure the current code is ok, I totally
         dislike that s390 is the only architecture being special here;
         especially considering that there was a lengthly discussion about
         this topic and the outcome was not to use the builtins. Therefore
         open-code atomic ops again with inline assembly and switch to gcc
         builtins as soon as other architectures are doing.
      
       - couple of other changes to atomic and cmpxchg, and use
         atomic-instrumented.h for KASAN.
      
       - separate zbus creation, registration, and scanning in our PCI code
         which allows for cleaner and easier handling.
      
       - a rather large change to the vfio-ap code to fix circular locking
         dependencies when updating crypto masks.
      
       - move QAOB handling from qdio layer down to drivers.
      
       - add CRW inject facility to common I/O layer. This adds debugs files
         which allow to generate artificial events from user space for testing
         purposes.
      
       - increase SCLP console line length from 80 to 320 characters to avoid
         odd wrapped lines.
      
       - add protected virtualization guest and host indication files, which
         indicate either that a guest is running in pv mode or if the
         hypervisor is capable of starting pv guests.

      Fix misc new gcc warnings · e7c6e405
      Linus Torvalds authored
      It seems like Fedora 34 ends up enabling a few new gcc warnings, notably
      "-Wstringop-overread" and "-Warray-parameter".
      
      Both of them cause what seem to be valid warnings in the kernel, where
      we have array size mismatches in function arguments (that are no longer
      just silently converted to a pointer to element, but actually checked).
      
      This fixes most of the trivial ones, by making the function declaration
      match the function definition, and in the case of intel_pm.c, removing
      the over-specified array size from the argument declaration.
      
      At least one 'stringop-overread' warning remains in the i915 driver, but
      that one doesn't have the same obvious trivial fix, and may or may not
      actually be indicative of a bug.
      
      [ It was a mistake to upgrade one of my machines to Fedora 34 while
        being busy with the merge window, but if this is the extent of the
        compiler upgrade problems, things are better than usual    - Linus ]

      Pull AFS updates from David Howells:
       "Use the new netfs lib.
      
        Begin the process of overhauling the use of the fscache API by AFS and
        the introduction of support for features such as Transparent Huge
        Pages (THPs).
      
         - Add some support for THPs, including using core VM helper functions
           to find details of pages.
      
         - Use the ITER_XARRAY I/O iterator to mediate access to the pagecache
           as this handles THPs and doesn't require allocation of large bvec
           arrays.
      
         - Delegate address_space read/pre-write I/O methods for AFS to the
           netfs helper library. A method is provided to the library that
           allows it to issue a read against the server.
      
           This includes a change in use for PG_fscache (it now indicates a
           DIO write in progress from the marked page), so a number of waits
           need to be deployed for it.
      
         - Split the core AFS writeback function to make it easier to modify
           in future patches to handle writing to the cache. [This might
           feasibly make more sense moved out into my fscache-iter branch].
      
        I've tested these with "xfstests -g quick" against an AFS volume
        (xfstests needs patching to make it work). With this, AFS without a
        cache passes all expected xfstests; with a cache, there's an extra
        failure, but that's also there before these patches. Fixing that
        probably requires a greater overhaul (as can be found on my
        fscache-iter branch, but that's for a later time).
      
        Thanks should go to Marc Dionne and Jeff Altman of AuriStor for
        exercising the patches in their test farm also"

      Pull network filesystem helper library updates from David Howells:
       "Here's a set of patches for 5.13 to begin the process of overhauling
        the local caching API for network filesystems. This set consists of
        two parts:
      
        (1) Add a helper library to handle the new VM readahead interface.
      
            This is intended to be used unconditionally by the filesystem
            (whether or not caching is enabled) and provides a common
            framework for doing caching, transparent huge pages and, in the
            future, possibly fscrypt and read bandwidth maximisation. It also
            allows the netfs and the cache to align, expand and slice up a
            read request from the VM in various ways; the netfs need only
            provide a function to read a stretch of data to the pagecache and
            the helper takes care of the rest.
      
        (2) Add an alternative fscache/cachfiles I/O API that uses the kiocb
            facility to do async DIO to transfer data to/from the netfs's
            pages, rather than using readpage with wait queue snooping on one
            side and vfs_write() on the other. It also uses less memory, since
            it doesn't do buffered I/O on the backing file.
      
            Note that this uses SEEK_HOLE/SEEK_DATA to locate the data
            available to be read from the cache. Whilst this is an improvement
            from the bmap interface, it still has a problem with regard to a
            modern extent-based filesystem inserting or removing bridging
            blocks of zeros. Fixing that requires a much greater overhaul.
      
        This is a step towards overhauling the fscache API. The change is
        opt-in on the part of the network filesystem. A netfs should not try
        to mix the old and the new API because of conflicting ways of handling
        pages and the PG_fscache page flag and because it would be mixing DIO
        with buffered I/O. Further, the helper library can't be used with the
        old API.
      
        This does not change any of the fscache cookie handling APIs or the
        way invalidation is done at this time.
      
        In the near term, I intend to deprecate and remove the old I/O API
        (fscache_allocate_page{,s}(), fscache_read_or_alloc_page{,s}(),
        fscache_write_page() and fscache_uncache_page()) and eventually
        replace most of fscache/cachefiles with something simpler and easier
        to follow.
      
        This patchset contains the following parts:
      
         - Some helper patches, including provision of an ITER_XARRAY iov
           iterator and a function to do readahead expansion.
      
         - Patches to add the netfs helper library.
      
         - A patch to add the fscache/cachefiles kiocb API.
      
         - A pair of patches to fix some review issues in the ITER_XARRAY and
           read helpers as spotted by Al and Willy.
      
        Jeff Layton has patches to add support in Ceph for this that he
        intends for this merge window. I have a set of patches to support AFS
        that I will post a separate pull request for.
      
        With this, AFS without a cache passes all expected xfstests; with a
        cache, there's an extra failure, but that's also there before these
        patches. Fixing that probably requires a greater overhaul. Ceph also
        passes the expected tests.
      
        I also have patches in a separate branch to tidy up the handling of
        PG_fscache/PG_private_2 and their contribution to page refcounting in
        the core kernel here, but I haven't included them in this set and will
        route them separately"

       "This builds on last cycle's LTO work, and allows the arm64 kernels to
        be built with Clang's Control Flow Integrity feature. This feature has
        happily lived in Android kernels for almost 3 years[1], so I'm excited
        to have it ready for upstream.
      
        The wide diffstat is mainly due to the treewide fixing of mismatched
        list_sort prototypes. Other things in core kernel are to address
        various CFI corner cases. The largest code portion is the CFI runtime
        implementation itself (which will be shared by all architectures
        implementing support for CFI). The arm64 pieces are Acked by arm64
        maintainers rather than coming through the arm64 tree since carrying
        this tree over there was going to be awkward.
      
        CFI support for x86 is still under development, but is pretty close.
        There are a handful of corner cases on x86 that need some improvements
        to Clang and objtool, but otherwise works well.
      
        Summary:
      
         - Clean up list_sort prototypes (Sami Tolvanen)
      
         - Introduce CONFIG_CFI_CLANG for arm64 (Sami Tolvanen)"
