From 3241f22da85d26505b39f525a88f52ebd1235975 Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Fri, 10 Sep 2010 17:30:45 +0200 Subject: [PATCH] KVM: MMU: Let is_rsvd_bits_set take mmu context instead of vcpu This patch changes is_rsvd_bits_set() function prototype to take only a kvm_mmu context instead of a full vcpu.
