Pull arm64 updates from Catalin Marinas:
 "Apart from the arm64-specific bits (core arch and perf, new arm64
  selftests), it touches the generic cow_user_page() (reviewed by
  Kirill) together with a macro for x86 to preserve the existing
  behaviour on this architecture.

  Summary:

   - On ARMv8 CPUs without hardware updates of the access flag, avoid
     failing cow_user_page() on PFN mappings if the pte is old. The
     patches introduce an arch_faults_on_old_pte() macro, defined as
     false on x86. When true, cow_user_page() makes the pte young before
     attempting __copy_from_user_inatomic().

   - Covert the synchronous exception handling paths in
     arch/arm64/kernel/entry.S to C.

   - FTRACE_WITH_REGS support for arm64.

   - ZONE_DMA re-introduced on arm64 to support Raspberry Pi 4

   - Several kselftest cases specific to arm64, together with a
     MAINTAINERS update for these files (moved to the ARM64 PORT entry).

   - Workaround for a Neoverse-N1 erratum where the CPU may fetch stale
     instructions under certain conditions.

   - Workaround for Cortex-A57 and A72 errata where the CPU may
     speculatively execute an AT instruction and associate a VMID with
     the wrong guest page tables (corrupting the TLB).

   - Perf updates for arm64: additional PMU topologies on HiSilicon
     platforms, support for CCN-512 interconnect, AXI ID filtering in
     the IMX8 DDR PMU, support for the CCPI2 uncore PMU in ThunderX2.

   - GICv3 optimisation to avoid a heavy barrier when accessing the
     ICC_PMR_EL1 register.

   - ELF HWCAP documentation updates and clean-up.

   - SMC calling convention conduit code clean-up.

   - KASLR diagnostics printed during boot

   - NVIDIA Carmel CPU added to the KPTI whitelist

   - Some arm64 mm clean-ups: use generic free_initrd_mem(), remove
     stale macro, simplify calculation in __create_pgd_mapping(), typos.

Pull btrfs updates from David Sterba:
 "User visible changes:
   - new block group profiles: RAID1 with 3- and 4- copies
       - RAID1 in btrfs has always 2 copies, now add support for 3 and 4
       - this is an incompat feature (named RAID1C34)
       - recommended use of RAID1C3 is replacement of RAID6 profile on
         metadata, this brings a more reliable resiliency against 2
         device loss/damage

   - support for new checksums
       - per-filesystem, set at mkfs time
       - fast hash (crc32c successor): xxhash, 64bit digest
       - strong hashes (both 256bit): sha256 (slower, FIPS), blake2b
         (faster)
       - the blake2b module goes via the crypto tree, btrfs.ko has a
         soft dependency

   - speed up lseek, don't take inode locks unnecessarily, this can
     speed up parallel SEEK_CUR/SEEK_SET/SEEK_END by 80%

   - send:
       - allow clone operations within the same file
       - limit maximum number of sent clone references to avoid slow
         backref walking

   - error message improvements: device scan prints process name and PID

  Core changes:
   - cleanups
       - remove unique workqueue helpers, used to provide a way to avoid
         deadlocks in the workqueue code, now done in a simpler way
       - remove lots of indirect function calls in compression code
       - extent IO tree code moved out of extent_io.c
       - cleanup backup superblock handling at mount time
       - transaction life cycle documentation and cleanups
       - locking code cleanups, annotations and documentation
       - add more cold, const, pure function attributes
       - removal of unused or redundant struct members or variables

   - new tree-checker sanity tests
       - try to detect missing INODE_ITEM, cross-reference checks of
         DIR_ITEM, DIR_INDEX, INODE_REF, and XATTR_* items

   - remove own bio scheduling code (used to avoid checksum submissions
     being stuck behind other IO), replaced by cgroup controller-based
     code to allow better control and avoid priority inversions in cases
     where the custom and cgroup scheduling disagreed

  Fixes:
   - avoid getting stuck during cyclic writebacks

   - fix trimming of ranges crossing block group boundaries

   - fix rename exchange on subvolumes, all involved subvolumes need to

Pull io_uring updates from Jens Axboe:
 "A lot of stuff has been going on this cycle, with improving the
  support for networked IO (and hence unbounded request completion
  times) being one of the major themes. There's been a set of fixes done
  this week, I'll send those out as well once we're certain we're fully
  happy with them.

  This contains:

   - Unification of the "normal" submit path and the SQPOLL path (Pavel)

   - Support for sparse (and bigger) file sets, and updating of those
     file sets without needing to unregister/register again.

   - Independently sized CQ ring, instead of just making it always 2x
     the SQ ring size. This makes it more flexible for networked
     applications.

   - Support for overflowed CQ ring, never dropping events but providing
     backpressure on submits.

   - Add support for absolute timeouts, not just relative ones.

   - Support for generic cancellations. This divorces io_uring from
     workqueues as well, which additionally gets us one step closer to
     generic async system call support.

   - With cancellations, we can support grabbing the process file table
     as well, just like we do mm context. This allows support for system
     calls that create file descriptors, like accept4() support that's
     built on top of that.

   - Support for io_uring tracing (Dmitrii)

   - Support for linked timeouts. These abort an operation if it isn't
     completed by the time noted in the linke timeout.

   - Speedup tracking of poll requests

   - Various cleanups making the coder easier to follow (Jackie, Pavel,
     Bob, YueHaibing, me)

   - Update MAINTAINERS with new io_uring list"

fdget_pos() is used by file operations that will read and update f_pos:
things like "read()", "write()" and "lseek()" (but not, for example,
"pread()/pwrite" that get their file positions elsewhere).

However, it had two separate escape clauses for this, because not
everybody wants or needs serialization of the file position.

The first and most obvious case is the "file descriptor doesn't have a
position at all", ie a stream-like file.  Except we didn't actually use
FMODE_STREAM, but instead used FMODE_ATOMIC_POS.  The reason for that
was that FMODE_STREAM didn't exist back in the days, but also that we
didn't want to mark all the special cases, so we only marked the ones
that _required_ position atomicity according to POSIX - regular files
and directories.

The case one was intentionally lazy, but now that we _do_ have
FMODE_STREAM we could and should just use it.  With the change to use
FMODE_STREAM, there are no remaining uses for FMODE_ATOMIC_POS, and all
the code to set it is deleted.

Any cases where we don't want the serialization because the driver (or
subsystem) doesn't use the file position should just be updated to do
"stream_open()".  We've done that for all the obvious and common
situations, we may need a few more.  Quoting Kirill Smelkov in the
original FMODE_STREAM thread (see link below for full email):

 "And I appreciate if people could help at least somehow with "getting
  rid of mixed case entirely" (i.e. always lock f_pos_lock on
  !FMODE_STREAM), because this transition starts to diverge from my
  particular use-case too far. To me it makes sense to do that
  transition as follows:

   - convert nonseekable_open -> stream_open via stream_open.cocci;
   - audit other nonseekable_open calls and convert left users that
     truly don't depend on position to stream_open;
   - extend stream_open.cocci to analyze alloc_file_pseudo as well (this
     will cover pipes and sockets), or maybe convert pipes and sockets
     to FMODE_STREAM manually;
   - extend stream_open.cocci to analyze file_operations that use
     no_llseek or noop_llseek, but do not use nonseekable_open or
     alloc_file_pseudo. This might find files that have stream semantic
     but are opened differently;
   - extend stream_open.cocci to analyze file_operations whose
     .read/.write do not use ppos at all (independently of how file was
     opened);
   - ...
   - after that remove FMODE_ATOMIC_POS and always take f_pos_lock if
     !FMODE_STREAM;
   - gather bug reports for deadlocked read/write and convert missed
     cases to FMODE_STREAM, probably extending stream_open.cocci along
     the road to catch similar cases

  i.e. always take f_pos_lock unless a file is explicitly marked as
  being stream, and try to find and cover all files that are streams"

We have not done the "extend stream_open.cocci to analyze
alloc_file_pseudo" as well, but the previous commit did manually handle
the case of pipes and sockets.

The other case where we can avoid locking f_pos is the "this file
descriptor only has a single user and it is us, and thus there is no
need to lock it".

The second test was correct, although a bit subtle and worth just
re-iterating here.  There are two kinds of other sources of references
to the same file descriptor: file descriptors that have been explicitly
shared across fork() or with dup(), and file tables having elevated
reference counts due to threading (or explicit file sharing with
clone()).

The first case would have incremented the file count explicitly, and in
the second case the previous __fdget() would have incremented it for us
and set the FDPUT_FPUT flag.

But in both cases the file count would be greater than one, so the
"file_count(file) > 1" test catches both situations.  Also note that if
file_count is 1, that also means that no other thread can have access to
the file table, so there also cannot be races with concurrent calls to
dup()/fork()/clone() that would increment the file count any other way.

In commit 3975b097 ("convert stream-like files -> stream_open, even
if they use noop_llseek") Kirill used a coccinelle script to change
"nonseekable_open()" to "stream_open()", which changed the trivial cases
of stream-like file descriptors to the new model with FMODE_STREAM.

However, the two big cases - sockets and pipes - don't actually have
that trivial pattern at all, and were thus never converted to
FMODE_STREAM even though it makes lots of sense to do so.

That's particularly true when looking forward to the next change:
getting rid of FMODE_ATOMIC_POS entirely, and just using FMODE_STREAM to
decide whether f_pos updates are needed or not.  And if they are, we'll
always do them atomically.

This came up because KCSAN (correctly) noted that the non-locked f_pos
updates are data races: they are clearly benign for the case where we
don't care, but it would be good to just not have that issue exist at
all.

Note that the reason we used FMODE_ATOMIC_POS originally is that only
doing it for the minimal required case is "safer" in that it's possible
that the f_pos locking can cause unnecessary serialization across the
whole write() call.  And in the worst case, that kind of serialization
can cause deadlock issues: think writers that need readers to empty the
state using the same file descriptor.

[ Note that the locking is per-file descriptor - because it protects
  "f_pos", which is obviously per-file descriptor - so it only affects
  cases where you literally use the same file descriptor to both read
  and write.

  So a regular pipe that has separate reading and writing file
  descriptors doesn't really have this situation even though it's the
  obvious case of "reader empties what a bit writer concurrently fills"

  But we want to make pipes as being stream-line anyway, because we
  don't want the unnecessary overhead of locking, and because a named
  pipe can be (ab-)used by reading and writing to the same file
  descriptor. ]

There are likely a lot of other cases that might want FMODE_STREAM, and
looking for ".llseek = no_llseek" users and other cases that don't have
an lseek file operation at all and making them use "stream_open()" might
be a good idea.  But pipes and sockets are likely to be the two main
cases.

Ugh, I really dropped the ball on this one :\. So as it turns out RMI4
works perfectly fine on the X1 Extreme Gen 2 except for one thing I
didn't notice because I usually use the trackpoint: clicking with the
touchpad. Somehow this is broken, in fact we don't even seem to indicate
BTN_LEFT as a valid event type for the RMI4 touchpad. And, I don't even
see any RMI4 events coming from the touchpad when I press down on it.
This only seems to work for PS/2 mode.

Since that means we have a regression, and PS/2 mode seems to work fine
for the time being - revert this for now. We'll have to do a more
thorough investigation on this.

Once udp stack has set the UDP_SKB_IS_STATELESS flag, later skb free
assumes all skb head state has been dropped already.

This will leak the extension memory in case the skb has extensions other
than the ipsec secpath, e.g. bridge nf data.

To fix this, set the UDP_SKB_IS_STATELESS flag only if we don't have
extensions or if the extension space can be free'd.

Pull power management regression fix from Rafael Wysocki:
 "Fix problems with switching cpufreq drivers on some x86 systems with
  ACPI (and with changing the operation modes of the intel_pstate driver
  on those systems) introduced by recent changes related to the
  management of frequency limits in cpufreq"

* tag 'pm-5.4-final' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  PM: QoS: Invalidate frequency QoS requests after removal

Pull drm fixes from Dave Airlie:
 "Two sets of fixes in here, one for amdgpu, and one for i915.

  The amdgpu ones are pretty small, i915's CI system seems to have a few
  problems in the last week or so, there is one major regression fix for
  fb_mmap, but there are a bunch of other issues fixed in there as well,
  oops, screen flashes and rcu related.

  amdgpu:
   - Remove experimental flag for navi14
   - Fix confusing power message failures on older VI parts
   - Hang fix for gfxoff when using the read register interface
   - Two stability regression fixes for Raven

  i915:
   - Fix kernel oops on dumb_create ioctl on no crtc situation
   - Fix bad ugly colored flash on VLV/CHV related to gamma LUT update
   - Fix unity of the frequencies reported on PMU
   - Fix kernel oops on set_page_dirty using better locks around it
   - Protect the request pointer with RCU to prevent it being freed
     while we might need still
   - Make pool objects read-only
   - Restore physical addresses for fb_map to avoid corrupted page
     table"
