Linus,

  Merge tag 'kvmarm-fixes-5.17-4' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD (2022-02-25 09:49:30 -0500)

----------------------------------------------------------------
The bigger part of the change is a revert for x86 hosts.  Here the
second patch was supposed to fix the first, but in reality it was
just as broken, so both have to go.

x86 host:

* Revert incorrect assumption that cr3 changes come with preempt notifier
  callbacks (they don't when static branches are changed, for example)

ARM host:

* Correctly synchronise PMR and co on PSCI CPU_SUSPEND

* Skip tests that depend on GICv3 when the HW isn't available
