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)
