Merge tag 'kvmarm-fixes-6.3-4' of git://git./linux/kernel/git/kvmarm/kvmarm into HEAD

KVM/arm64 fixes for 6.3, part #4

 - 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.
