Subject: [PATCH V2 0/8] kvm: x86/mmu: Share the same code to invalidate each vTLB entry 

From: Lai Jiangshan <jiangshan.ljs@...group.com>

FNAME(invlpg) and FNAME(sync_page) invalidate vTLB entries but in
slightly different methods.

Make them use the same method and share the same code.

[V1]: https://lore.kernel.org/lkml/20230105095848.6061-1-jiangshanlai@gmail.com/

Lai Jiangshan (8):
  kvm: x86/mmu: Use KVM_MMU_ROOT_XXX for kvm_mmu_invalidate_gva()
  kvm: x86/mmu: Use kvm_mmu_invalidate_gva() in kvm_mmu_invpcid_gva()
  kvm: x86/mmu: Use kvm_mmu_invalidate_gva() in
    nested_ept_invalidate_addr()
  kvm: x86/mmu: Set mmu->sync_page as NULL for direct paging
  kvm: x86/mmu: Move the code out of FNAME(sync_page)'s loop body into
    mmu.c
  kvm: x86/mmu: Remove FNAME(invlpg)
  kvm: x86/mmu: Reduce the update to the spte in FNAME(sync_page)
  kvm: x86/mmu: Remove @no_dirty_log from FNAME(prefetch_gpte)
