Subject: [PATCH 0/3] KVM: x86/mmu: Clean up kvm_zap_gfn_range()

Fix overzealous flushing in kvm_zap_gfn_range(), and clean up the mess
that it's become by extracting the legacy MMU logic to a separate
helper.

Sean Christopherson (3):
  KVM: x86/mmu: Drop a redundant, broken remote TLB flush
  KVM: x86/mmu: Drop a redundant remote TLB flush in kvm_zap_gfn_range()
  KVM: x86/mmu: Extract zapping of rmaps for gfn range to separate
    helper
