9ee850acd2 x86_64: Remove pointless set_64bit() usage
The use of set_64bit() in X86_64 only code is pretty pointless, seeing
how it's a direct assignment. Remove all this nonsense.

b7301f2010 x86/mm/pae: Be consistent with pXXp_get_and_clear()
Given that ptep_get_and_clear() uses cmpxchg8b, and that should be by
far the most common case, there's no point in having an optimized
variant for pmd/pud.

Introduce the pxx_xchg64() helper to implement the common logic once.

1180e732c9 mm/gup: Fix the lockless PMD access
On architectures where the PTE/PMD is larger than the native word size

97e3d26b5e x86/mm: Randomize per-cpu entry area
Seth found that the CPU-entry-area; the piece of per-cpu data that is
mapped into the userspace page-tables for kPTI is not subject to any
randomization -- irrespective of kASLR settings.

On x86_64 a whole P4D (512 GB) of virtual address space is reserved for
this structure, which is plenty large enough to randomize things a
little.

As such, use a straight forward randomization scheme that avoids
duplicates to spread the existing CPUs over the available space.

3f148f3318 x86/kasan: Map shadow for percpu pages on demand
KASAN maps shadow for the entire CPU-entry-area:
  [CPU_ENTRY_AREA_BASE, CPU_ENTRY_AREA_BASE + CPU_ENTRY_AREA_MAP_SIZE]

This will explode once the per-cpu entry areas are randomized since it
will increase CPU_ENTRY_AREA_MAP_SIZE to 512 GB and KASAN fails to
allocate shadow for such big area.

Fix this by allocating KASAN shadow only for really used cpu entry area
addresses mapped by cea_map_percpu_pages()

Thanks to the 0day folks for finding and reporting this to be an issue.

c68f72900a btrfs: fix leak of fs devices after removing btrfs module
When removing the btrfs module we are not calling btrfs_cleanup_fs_uuids()
which results in leaking btrfs_fs_devices structures and other resources.
This is a regression recently introduced by a refactoring of the module
initialization and exit sequence, which simply removed the call to
btrfs_cleanup_fs_uuids() in the exit path, resulting in the leaks.

So fix this by calling btrfs_cleanup_fs_uuids() at exit_btrfs_fs().

44da203206 drm/i915/dg2: Return Wa_22012654132 to just specific steppings
Programming of the ENABLE_PREFETCH_INTO_IC bit originally showed up in
both the general DG2 tuning guide (applicable to all DG2
variants/steppings) and under Wa_22012654132 (applicable only to
specific steppings).  It has now been removed from the tuning guide, and
the guidance is to only program it in the specific steppings associated
with the workaround.

c0cd1d5417 Revert "arm64: errata: Workaround possible Cortex-A715 [ESR|FAR]_ELx corruption"
This reverts commit 44ecda71fd.

All versions of this patch on the mailing list, including the version
that ended up getting merged, have portions of code guarded by the
non-existent CONFIG_ARM64_WORKAROUND_2645198 option. Although Anshuman
says he tested the code with some additional debug changes [1], I'm
hesitant to fix the CONFIG option and light up a bunch of code right
before I (and others) disappear for the end of year holidays, during
which time we won't be around to deal with any fallout.

So revert the change for now. We can bring back a fixed, tested version
for a later -rc when folks are thinking about things other than trees
and turkeys.

c0f234ff90 gpio: updates for v6.2
GPIO core:
 - teach gpiolib to work with software nodes for HW description
 - remove ARCH_NR_GPIOS treewide as we no longer impose any limit on the number
   of GPIOS since the allocation became entirely dynamic
 - add support for HW quirks for Cirrus CS42L56 codec, Marvell NFC controller,
   Freescale PCIe and Ethernet controller, Himax LCDs and Mediatek mt2701
 - refactor OF quirk code
 - some general refactoring of the OF and ACPI code, adding new helpers, minor
   tweaks and fixes, making fwnode usage consistent etc.
 
 GPIO uAPI:
 - fix an issue where the user-space can trigger a NULL-pointer dereference in
   the kernel by opening a device file, forcing a driver unbind and then calling
   one of the syscalls on the associated file descriptor
 
 New drivers:
 - add gpio-latch: a new GPIO multiplexer based on latches connected to other
   GPIOs
 
 Driver updates:
 - convert i2c GPIO expanders to using .probe_new()
 - drop the gpio-sta2x11 driver
 - factor out common code for the ACCES IDIO-16 family of controllers and use
   this new library wherever applicable in drivers
 - add DT support to gpio-hisi
 - allow building gpio-davinci as a module and increase its maxItems property
 - add support for a new model to gpio-pca9570
 - other minor changes to various drivers

_ATOM_GPIO_VOLTAGE_OBJECT_V3 and refactor the rest of the code accordingly.

It's worth mentioning that doing a build before/after this patch
