Patch series "set clang minimum version to 10.0.1", v3.

Adds a compile time #error to compiler-clang.h setting the effective
minimum supported version to clang 10.0.1.  A separate patch has already
been picked up into the Documentation/ tree also confirming the version.

Next are a series of reverts. One for 32b arm is a partial revert.

Then Marco suggested fixes to KASAN docs.

Finally, improve the warning for GCC too as per Kees.

This patch (of 7):

During Plumbers 2020, we voted to just support the latest release of Clang
for now.  Add a compile time check for this.

We plan to remove workarounds for older versions now, which will break in
subtle and not so subtle ways.

Pull GPIO updates from Linus Walleij:
 "This time very little driver changes but lots of core changes.

  We have some interesting cooperative work for ARM and Intel alike,
  making the GPIO subsystem more and more suitable for industrial
  systems and the like, in addition to the in-kernel users.

  We touch driver core (device properties) and lib/* by adding one
  simple string array free function, these are authored by Andy
  Shevchenko who is a well known and recognized core helpers maintainers
  so this should be fine.

  We also see some Android GKI-related modularization in the MXC
  drivers.

  Core changes:

   - The big core change is the updated (v2) userspace character device
     API.

     This corrects badly designed 64-bit alignment around the line
     events. We also add the debounce request feature. This echoes the
     often quotes passage from Frederick Brooks "The mythical man-month"
     to always throw one away, which we have seen before in things such
     as V4L2. So we put in a new one and deprecate and obsolete the old
     one.

   - All example tools in tools/gpio/* are migrated to the new API to
     set a good example. The libgpiod userspace library has been
     augmented to use this new API pretty much from day 1.

   - Some misc API hardening by using strn* function calls has been
     added as well.

   - Use the simpler IDA interface for GPIO chip instance enumeration.

   - Add device core function for counting string arrays in device
     properties.

   - Provide a generic library function kfree_strarray() that can be
     used throughout the kernel.

  Driver enhancements:

   - The DesignWare dwapb-gpio driver has been enhanced and now uses the
     IRQ handling in the gpiolib core.

   - The mockup and aggregator drivers have seen some substantial code
     clean-up and now use more of the core kernel inftrastructure.

   - Misc cleanups using dev_err_probe().

   - The MXC drivers (Freescale/NXP) can now be built modularized, which
     makes modularized GKI Android kernels happy"

Pull btrfs updates from David Sterba:
 "Mostly core updates with a few user visible bits and fixes.

  Hilights:

   - fsync performance improvements
      - less contention of log mutex (throughput +4%, latency -14%,
        dbench with 32 clients)
      - skip unnecessary commits for link and rename (throughput +6%,
        latency -30%, rename latency -75%, dbench with 16 clients)
      - make fast fsync wait only for writeback (throughput +10..40%,
        runtime -1..-20%, dbench with 1 to 64 clients on various
        file/block sizes)

   - direct io is now implemented using the iomap infrastructure, that's
     the main part, we still have a workaround that requires an iomap
     API update, coming in 5.10

   - new sysfs exports:
      - information about the exclusive filesystem operation status
        (balance, device add/remove/replace, ...)
      - supported send stream version

  Core:

   - use ticket space reservations for data, fair policy using the same
     infrastructure as metadata

   - preparatory work to switch locking from our custom tree locks to
     standard rwsem, now the locking context is propagated to all
     callers, actual switch is expected to happen in the next dev cycle

   - seed device structures are now using list API

   - extent tracepoints print proper tree id

   - unified range checks for extent buffer helpers

   - send: avoid using temporary buffer for copying data

   - remove unnecessary RCU protection from space infos

   - remove unused readpage callback for metadata, enabling several
     cleanups

   - replace indirect function calls for end io hooks and remove
     extent_io_ops completely

  Fixes:

   - more lockdep warning fixes

   - fix qgroup reservation for delayed inode and an occasional
     reservation leak for preallocated files

   - fix device replace of a seed device

   - fix metadata reservation for fallocate that leads to transaction
     aborts

   - reschedule if necessary when logging directory items or when
     cloning lots of extents

   - tree-checker: fix false alert caused by legacy btrfs root item

   - send: fix rename/link conflicts for orphanized inodes

   - properly initialize device stats for seed devices

   - skip devices without magic signature when mounting

  Other:

   - error handling improvements, BUG_ONs replaced by proper handling,
     fuzz fixes

   - various function parameter cleanups

   - various W=1 cleanups

   - error/info messages improved

  Mishaps:

   - commit 62cf5391 ("btrfs: move btrfs_rm_dev_replace_free_srcdev
     outside of all locks") is a rebase leftover after the patch got
     merged to 5.9-rc8 as a466c85e ("btrfs: move
     btrfs_rm_dev_replace_free_srcdev outside of all locks"), the
     remaining part is trivial and the patch is in the middle of the

Clang-11 shipped support for outputs to asm goto statments along the
fallthrough path.  Double up some of the get_user() and related macros
to be able to take advantage of this extended GNU C extension. This
should help improve the generated code's performance for these accesses.

Instead of inlining the stac/mov/clac sequence (which also requires
individual exception table entries and several asm instruction
alternatives entries), just generate "call __put_user_nocheck_X" for the
__put_user() cases, the same way we changed __get_user earlier.

Unlike the get_user() case, we didn't have the same nice infrastructure
to just generate the call with a single case, so this actually has to
change some of the infrastructure in order to do this.  But that only
cleans up the code further.

So now, instead of using a case statement for the sizes, we just do the
same thing we've done on the get_user() side for a long time: use the
size as an immediate constant to the asm, and generate the asm that way
directly.

In order to handle the special case of 64-bit data on a 32-bit kernel, I
needed to change the calling convention slightly: the data is passed in
%eax[:%edx], the pointer in %ecx, and the return value is also returned
in %ecx.  It used to be returned in %eax, but because of how %eax can
now be a double register input, we don't want mix that with a
single-register output.

The actual low-level asm is easier to handle: we'll just share the code
between the checking and non-checking case, with the non-checking case
jumping into the middle of the function.  That may sound a bit too
special, but this code is all very very special anyway, so...

Instead of inlining the whole stac/lfence/mov/clac sequence (which also
requires individual exception table entries and several asm instruction
alternatives entries), just generate "call __get_user_nocheck_X" for the
__get_user() cases.

We can use all the same infrastructure that we already do for the
regular "get_user()", and the end result is simpler source code, and
much simpler code generation.

It also means that when I introduce asm goto with input for
"unsafe_get_user()", there are no nasty interactions with the
__get_user() code.
