[v2,5/7] KVM: x86/MMU: Use gfn_t in kvm_flush_remote_tlbs_range()

Commit Message

David Matlack Jan. 26, 2023, 6:40 p.m. UTC

Use gfn_t instead of u64 for the start_gfn parameter to
kvm_flush_remote_tlbs_range(), since that is the standard type for GFNs
throughout KVM.

No functional change intended.
