Pull kvm fixes from Paolo Bonzini:
"A bit late... I got sidetracked by back-from-vacation routines and
conferences. 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.
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"
