Merge tag 'kvm-x86-vmx-6.12' of https://github.com/kvm-x86/linux into HEAD
KVM VMX changes for 6.12:
- Set FINAL/PAGE in the page fault error code for EPT Violations if and only
if the GVA is valid. If the GVA is NOT valid, there is no guest-side page
table walk and so stuffing paging related metadata is nonsensical.
- Fix a bug where KVM would incorrectly synthesize a nested VM-Exit instead of
emulating posted interrupt delivery to L2.
- Add a lockdep assertion to detect unsafe accesses of vmcs12 structures.
- Harden eVMCS loading against an impossible NULL pointer deref (really truly
should be impossible).
- Minor SGX fix and a cleanup.
