Merge tag 'kvm-x86-fixes-6.17-rcN' of https://github.com/kvm-x86/linux into HEAD
KVM x86 fix for 6.17-rcN
Sync the vTPR from the local APIC to the VMCB even when AVIC is active, to fix
a bug where host updates to the vTPR, e.g. via KVM_SET_LAPIC or emulation of a
guest access, effectively get lost and result in interrupt delivery issues in
the guest.
