From e37afc6ee5a6af9b334e2f214ec795e8bfaaaba5 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Tue, 19 May 2015 16:09:04 +0200 Subject: [PATCH] KVM: remove __gfn_to_pfn Most of the function that wrap it can be rewritten without it, except for gfn_to_pfn_prot. Just inline it into gfn_to_pfn_prot, and rewrite the other function on top of gfn_to_pfn_memslot*.
