Subject: [PATCH 2/2] KVM: Remove unused kvm_vcpu_gfn_to_pfn_atomic

From: "Dr. David Alan Gilbert" <linux@...blig.org>

The last use of kvm_vcpu_gfn_to_pfn_atomic was removed by commit
1bbc60d0c7e5 ("KVM: x86/mmu: Remove MMU auditing")

Remove it.

Note, I've not removed the example in,
  Documentation/virt/kvm/locking.rst
which I guess needs reworking; or maybe it's a reason to hold onto
this.
