Subject: [GIT PULL] (Many) KVM fixes for 5.15-rc4
Linus,
The following changes since commit 2da4a23599c263bd4a7658c2fe561cb3a73ea6ae:
KVM: selftests: Remove __NR_userfaultfd syscall fallback (2021-09-22 10:24:02 -0400)

Merge tag 'kvmarm-fixes-5.15-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into kvm-master (2021-09-24 06:04:42 -0400)
----------------------------------------------------------------
x86:
- missing TLB flush
- nested virtualization fixes for SMM (secure boot on nested hypervisor)
and other nested SVM fixes
- syscall fuzzing fixes
- live migration fix for AMD SEV
- mirror VMs now work for SEV-ES too
- fixes for reset
- possible out-of-bounds access in IOAPIC emulation
- fix enlightened VMCS on Windows 2022
ARM:
- Add missing FORCE target when building the EL2 object
- Fix a PMU probe regression on some platforms
Generic:
- KCSAN fixes
selftests:
- random fixes, mostly for clang compilation
----------------------------------------------------------------
A bit late... I got sidetracked by back-from-vacation routines first and
conferences second. But most of these patches are already a few weeks
old and things look more calm on the mailing list than what this pull
request would suggest.
