Merge tag 'kvm-x86-fixes-6.13-rcN' of https://github.com/kvm-x86/linux into HEAD

KVM x86 fixes for 6.13:

 - Disable AVIC on SNP-enabled systems that don't allow writes to the virtual
   APIC page, as such hosts will hit unexpected RMP #PFs in the host when
   running VMs of any flavor.

 - Fix a WARN in the hypercall completion path due to KVM trying to determine
   if a guest with protected register state is in 64-bit mode (KVM's ABI is to
   assume such guests only make hypercalls in 64-bit mode).

 - Allow the guest to write to supported bits in MSR_AMD64_DE_CFG to fix a
   regression with Windows guests, and because KVM's read-only behavior appears
   to be entirely made up.

 - Treat TDP MMU faults as spurious if the faulting access is allowed given the
   existing SPTE.  This fixes a benign WARN (other than the WARN itself) due to
   unexpectedly replacing a writable SPTE with a read-only SPTE.
