[GIT,PULL] arm64 updates for 5.18

Hi Linus,

I'm off for the rest of the week, so here is an early pull containing
the arm64 changes for 5.18. Summary in the tag, but there are some other
points worthy of note:

  - I had to merge in the spectre-bhb mitigations as they conflicted
    with what was already queued. These are the same commits (SHAs) as
    what you took upstream, so the pull request has ended up using that
    as a base.

  - We have a few shared branches. In particular:

      * Instruction encoder updates are shared with eBPF (Daniel
        Borkmann)

      * Symbol aliasing cleanups are shared with -tip (Peter Z)

      * Apple interrupt controller updates are shared with irqchip (Marc
        Zyngier)

    and these explain most of the changes straying outside of the usual
    directories.

  - The MTE coredump support conflicted pretty badly with the maple tree
    VMA list conversion from Liam, so we've got a funny conditional
    definition of VMA_ITERATOR() to make this easy to deal with. It's
    spent a while in -next and we'll drop it at -rc1.

Thanks, and please pull.

Will

----------------------------------------------------------------
arm64 updates for 5.18

- Support for including MTE tags in ELF coredumps

- Instruction encoder updates, including fixes to 64-bit immediate
  generation and support for the LSE atomic instructions

- Improvements to kselftests for MTE and fpsimd

- Symbol aliasing and linker script cleanups

- Reduce instruction cache maintenance performed for user mappings
  created using contiguous PTEs

- Support for the new "asymmetric" MTE mode, where stores are checked
  asynchronously but loads are checked synchronously

- Support for the latest pointer authentication algorithm ("QARMA3")

- Support for the DDR PMU present in the Marvell CN10K platform

- Support for the CPU PMU present in the Apple M1 platform

- Use the RNDR instruction for arch_get_random_{int,long}()

- Update our copy of the Arm optimised string routines for str{n}cmp()

- Fix signal frame generation for CPUs which have foolishly elected to
  avoid building in support for the fpsimd instructions

- Workaround for Marvell GICv3 erratum #38545

- Clarification to our Documentation (booting reqs. and MTE prctl())

- Miscellanous cleanups and minor fixes
