  A few minor-ish fixes related to GUEST_MEMFD that I am hoping to squeeze
into 6.8 as the they affect KVM's ABI (especially patch 1).

Sean Christopherson (5):
  KVM: Make KVM_MEM_GUEST_MEMFD mutually exclusive with KVM_MEM_READONLY
  KVM: x86: Update KVM_SW_PROTECTED_VM docs to make it clear they're a
    WIP
  KVM: x86/mmu: Restrict KVM_SW_PROTECTED_VM to the TDP MMU
  KVM: selftests: Create GUEST_MEMFD for relevant invalid flags
    testcases
  KVM: selftests: Add a testcase to verify GUEST_MEMFD and READONLY are
    exclusive

Applied ridiculously quickly to kvm-x86 guest_memfd_fixes, so as to get these
into -next before the weekend.  I purposely put these in a separate branch so
that I can squash fixes, reviews, etc., or drop the branch outright if Paolo
swoops in and grabs 'em.
