  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
