Pull KVM x86 fixes from Paolo Bonzini:

 - 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.

 - Emit a warning when KVM is configured with ignore_msrs=1 and also to
   hide the MSRs that the guest is looking for from the kernel logs.
   ignore_msrs can trick guests into assuming that certain processor
   features are present, and this in turn leads to bogus bug reports.
