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.
