Subject: [GIT PULL] KVM fixes for Linux 5.17-rc2
Linus,
The following changes since commit e2e83a73d7ce66f62c7830a85619542ef59c90e4:
docs: kvm: fix WARNINGs from api.rst (2022-01-20 12:13:35 -0500)
are available in the Git repository at:

Merge tag 'kvmarm-fixes-5.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD (2022-01-28 07:45:15 -0500)
----------------------------------------------------------------
Two larger x86 series:
* Redo incorrect fix for SEV/SMAP erratum
* Windows 11 Hyper-V workaround
Other x86 changes:
* Various x86 cleanups
* Re-enable access_tracking_perf_test
* Fix for #GP handling on SVM
* Fix for CPUID leaf 0Dh in KVM_GET_SUPPORTED_CPUID
* Fix for ICEBP in interrupt shadow
* Avoid false-positive RCU splat
* Enable Enlightened MSR-Bitmap support for real
ARM:
* Correctly update the shadow register on exception injection when
running in nVHE mode
* Correctly use the mm_ops indirection when performing cache invalidation
from the page-table walker
* Restrict the vgic-v3 workaround for SEIS to the two known broken
implementations
Generic code changes:
* Dead code cleanup
There will be another pull request for ARM fixes next week, but
those patches need a bit more soak time.
