Linus,
The following changes since commit 18c841e1f4112d3fb742aca3429e84117fcb1e1c:
KVM: x86: Retry page fault if MMU reload is pending and root has no sp (2021-12-19 19:38:58 +0100)

KVM: VMX: Wake vCPU when delivering posted IRQ even if vCPU == this vCPU (2021-12-21 12:39:03 -0500)
----------------------------------------------------------------
* Fix for compilation of selftests on non-x86 architectures
* Fix for kvm_run->if_flag on SEV-ES
* Fix for page table use-after-free if yielding during exit_mm()
* Improve behavior when userspace starts a nested guest with invalid state
* Fix missed wakeup with assigned devices but no VT-d posted interrupts
* Do not tell userspace to save/restore an unsupported PMU MSR
----------------------------------------------------------------
So, 5.16 really was a huge bug shakedown for KVM. Apart from the locking
changes in -rc4, almost everything that went in after -rc2 was Cc'ed
stable, including this pull request (which I guess is not a bad thing
for rc7).
You can't quite see it, but things do seem to have calmed down; these
patches as well as those in rc6 had actually been submitted a week or
so ago; one was a relatively old 5.17 change that turned out to fix a
bug. Since I'm taking some time off until right before the merge
window, I don't expect any more changes in 5.16. Thanks for putting up
with this weird KVM release cycle.
