Subject: [PATCH 0/8] KVM: gmem: Adding hooks for SEV and TDX

From: Isaku Yamahata <isaku.yamahata@...el.com>

This patch series for KVM guest memfd is to have common code base for SEV and
TDX.  Several minor fixes.  Based on this patch series, TDX KVM can defer page
clearing without mmu lock.

Isaku Yamahata (6):
  KVM: gmem: Make kvm_gmem_bind return EBADF on wrong fd
  KVM: gmem: removed duplicated kvm_gmem_init()
  KVM: gmem: Fix kvm_gmem_issue_arch_invalidate()
  KVM: gmem: protect kvm_mmu_invalidate_end()
  KVM: gmem: Avoid race with kvm_gmem_release and mmu notifier
  RFC: KVM: gmem: Guarantee the order of destruction

Michael Roth (2):
  KVM: gmem, x86: Add gmem hook for initializing private memory
  KVM: gmem, x86: Add gmem hook for invalidating private memory
