Subject: [PATCH 7/7] KVM: SVM: Ignore lower 12 bit of nested msrpm_pa
Date: Mon, 1 Mar 2010 15:34:40 +0100 [thread overview]
Message-ID: <1267454080-2513-8-git-send-email-joerg.roedel@amd.com> (raw)
In-Reply-To: <1267454080-2513-1-git-send-email-joerg.roedel@amd.com>
These bits are ignored by the hardware too. Implement this
for nested svm too.
