We need the bits of _TIF_WORK_MASK to be contiguous in order to to use
this as an immediate argument to an AND instruction in entry.S.

We happened to change these bits in commits:

  b5a5a01d ("arm64: uaccess: remove addr_limit_user_check()")
  192caabd ("arm64: add support for TIF_NOTIFY_SIGNAL")

which each worked in isolation, but the merge resolution in commit:

  005b2a9d ("Merge tag 'tif-task_work.arch-2020-12-14' of git://git.kernel.dk/linux-block")

happened to make the bits non-contiguous.

Fix this by moving TIF_NOTIFY_SIGNAL to be bit 6, which is contiguous
with the rest of _TIF_WORK_MASK.

Pull IOMMU updates from Will Deacon:
 "There's a good mixture of improvements to the core code and driver
  changes across the board.

  One thing worth pointing out is that this includes a quirk to work
  around behaviour in the i915 driver (see 65f746e8 ("iommu: Add
  quirk for Intel graphic devices in map_sg")), which otherwise
  interacts badly with the conversion of the intel IOMMU driver over to
  the DMA-IOMMU APU but has being fixed properly in the DRM tree.

  We'll revert the quirk later this cycle once we've confirmed that
  things don't fall apart without it.

   - Introduction of DOMAIN_ATTR_IO_PGTABLE_CFG for parameterising the

 "Fairly light set of changes this time around, and mostly some bits

   - Cleanups around iovec import (David Laight, Pavel)

   - Add timeout support for io_uring_enter(2), which enables us to

Pull TIF_NOTIFY_SIGNAL updates from Jens Axboe:
 "This sits on top of of the core entry/exit and x86 entry branch from
  the tip tree, which contains the generic and x86 parts of this work.

  Here we convert the rest of the archs to support TIF_NOTIFY_SIGNAL.

  With that done, we can get rid of JOBCTL_TASK_WORK from task_work and
  signal.c, and also remove a deadlock work-around in io_uring around
  knowing that signal based task_work waking is invoked with the sighand
  wait queue head lock.

  The motivation for this work is to decouple signal notify based
  task_work, of which io_uring is a heavy user of, from sighand. The
  sighand lock becomes a huge contention point, particularly for
  threaded workloads where it's shared between threads. Even outside of
  threaded applications it's slower than it needs to be.

  Roman Gershman <romger@amazon.com> reported that his networked
  workload dropped from 1.6M QPS at 80% CPU to 1.0M QPS at 100% CPU
  after io_uring was changed to use TIF_NOTIFY_SIGNAL. The time was all
  spent hammering on the sighand lock, showing 57% of the CPU time there
  [1].

  There are further cleanups possible on top of this. One example is
  TIF_PATCH_PENDING, where a patch already exists to use
  TIF_NOTIFY_SIGNAL instead. Hopefully this will also lead to more
  consolidation, but the work stands on its own as well"

   - bug fix: fail calculating the file hash, when a file not opened for
     read and the attempt to re-open it for read fails.

   - defer processing the "ima_appraise" boot command line option to
     avoid enabling different modes (e.g. fix, log) to when the secure
     boot flag is available on arm.

 "While we have a small number of SELinux patches for v5.11, there are a
  few changes worth highlighting:

   - Change the LSM network hooks to pass flowi_common structs instead

     full flowi struct and they do not have enough information to use it
     safely (missing information on the address family).

     This patch was discussed both with Herbert Xu (representing team
     netdev) and James Morris (representing team
     LSMs-other-than-SELinux).

   - Fix how we handle errors in inode_doinit_with_dentry() so that we
     attempt to properly label the inode on following lookups instead of
     continuing to treat it as unlabeled.

   - Tweak the kernel logic around allowx, auditallowx, and dontauditx
     SELinux policy statements such that the auditx/dontauditx are
     effective even without the allowx statement.

  Everything passes our test suite"

Merge tag 'asm-generic-timers-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic

Pull asm-generic cross-architecture timer cleanup from Arnd Bergmann:
 "This cleans up two ancient timer features that were never completed in
  the past, CONFIG_GENERIC_CLOCKEVENTS and CONFIG_ARCH_USES_GETTIMEOFFSET.

  There was only one user left for the ARCH_USES_GETTIMEOFFSET variant
  of clocksource implementations, the ARM EBSA110 platform. Rather than
  changing to use modern timekeeping, we remove the platform entirely as
  Russell no longer uses his machine and nobody else seems to have one
  any more.

  The conditional code for using arch_gettimeoffset() is removed as a
  result.

  For CONFIG_GENERIC_CLOCKEVENTS, there are still a couple of platforms
  not using clockevent drivers: parisc, ia64, most of m68k, and one Arm
  platform. These all do timer ticks slighly differently, and this gets
  cleaned up to the point they at least all call the same helper
  function.

  Kconfig, the polarity is now reversed, with the few remaining ones
  selecting LEGACY_TIMER_TICK instead"

 * kernel/fail_function.c:adjust_error_retval()

to accommodate for this change.

Handle EI_ETYPE_TRUE in both functions appropriately by

 * adjusting the return value to true (1) in adjust_error_retval().

Furthermore, simplify the logic of handling EI_ETYPE_NULL in
adjust_error_retval().

Filter out reboot_type and reboot_force which are x86 only, and also

This saves some space, and avoid confusing the user with settings which
