Subject: [GIT PULL] KVM fixes for 5.16-rc4
Linus,
The following changes since commit 136057256686de39cc3a07c2e39ef6bc43003ff6:
Linux 5.16-rc2 (2021-11-21 13:47:39 -0800)

KVM: fix avic_set_running for preemptable kernels (2021-11-30 07:40:48 -0500)
----------------------------------------------------------------
ARM64:
* Fix constant sign extension affecting TCR_EL2 and preventing
running on ARMv8.7 models due to spurious bits being set
* Fix use of helpers using PSTATE early on exit by always sampling
it as soon as the exit takes place
* Move pkvm's 32bit handling into a common helper
RISC-V:
* Fix incorrect KVM_MAX_VCPUS value
* Unmap stage2 mapping when deleting/moving a memslot
x86:
* Fix and downgrade BUG_ON due to uninitialized cache
* Many APICv and MOVE_ENC_CONTEXT_FROM fixes
* Correctly emulate TLB flushes around nested vmentry/vmexit
and when the nested hypervisor uses VPID
* Prevent modifications to CPUID after the VM has run
* Other smaller bugfixes
Generic:
* Memslot handling bugfixes
----------------------------------------------------------------
This is the large bugfix pull request that I mentioned just before rc2,
with the APICv and MOVE_ENC_CONTEXT_FROM/COPY_ENC_CONTEXT_FROM bug
shakedown. It missed rc3 due to Thanksgiving (half of the patches
are mine and I wanted to get reviews on them for obvious reasons).
Thanks,
Paolo
