Subject: [PATCH 09/18] KVM: MMU: Let is_rsvd_bits_set take mmu context instead of vcpu
Date: Wed, 3 Mar 2010 20:12:12 +0100	[thread overview]
Message-ID: <1267643541-451-10-git-send-email-joerg.roedel@amd.com> (raw)
In-Reply-To: <1267643541-451-1-git-send-email-joerg.roedel@amd.com>

This patch changes is_rsvd_bits_set() function prototype to
take only a kvm_mmu context instead of a full vcpu.
