[PATCH 0/7] KVM: MMU changes for TDX VE support

[Paolo Bonzini <pbonzini@redhat.com>]

Allow a non-zero value for non-present SPTE and removed SPTE,
so that TDX can set the "suppress VE" bit.  This is taken from
https://patchew.org/linux/20240416201935.3525739-1-pbonzini@redhat.com/
with review comments addressed:

- do not dereference an address from the VMCS to include #VE info
  in the dump

- fail hard if the #VE info page cannot be allocated
