From 116a0a23676e7d29b7747a53f819baaaf4b88575 Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Fri, 3 Dec 2010 11:45:49 +0100 Subject: [PATCH] KVM: SVM: Add clean-bit for intercetps, tsc-offset and pause filter count This patch adds the clean-bit for intercepts-vectors, the TSC offset and the pause-filter count to the appropriate places. The IO and MSR permission bitmaps are not subject to this bit.
