  Merge tag 'kvmarm-fixes-6.3-4' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD (2023-04-21 19:19:02 -0400)

(I checked and indeed last week's mishap was due to an incorrect push
_after_ I had generated the message and before I sent it.  I always
use "git request-pull", or more precisely a wrapper that generates the
mail headers and the "Linus," at the top, since I am clearly clumsy
enough with the automation that it provides...).

----------------------------------------------------------------
Two serious ARM fixes:

* Plug a buffer overflow due to the use of the user-provided register
  width for firmware regs. Outright reject accesses where the
  user register width does not match the kernel representation.

* Protect non-atomic RMW operations on vCPU flags against preemption,
  as an update to the flags by an intervening preemption could be lost.
