[GIT,PULL] KVM/arm64 updates for 5.16

Hi Paolo,

Here's the bulk of KVM/arm64 updates for 5.16. The changes are more or
less equaly split between new features (more pKVM stuff trickling in
as it gets written), a bunch of new selftests (timer, vgic), and bug
fixes.

Please pull,

	M.

The following changes since commit 9e1ff307c779ce1f0f810c7ecce3d95bbae40896:

----------------------------------------------------------------
KVM/arm64 updates for Linux 5.16

- More progress on the protected VM front, now with the full
  fixed feature set as well as the limitation of some hypercalls
  after initialisation.

- Cleanup of the RAZ/WI sysreg handling, which was pointlessly
  complicated

- Fixes for the vgic placement in the IPA space, together with a
  bunch of selftests

- More memcg accounting of the memory allocated on behalf of a guest

- Timer and vgic selftests

- Workarounds for the Apple M1 broken vgic implementation

- KConfig cleanups

- New kvmarm.mode=none option, for those who really dislike us
