[PATCH V2] 2.6.34: simple IOMMU API extension to check safe interrupt remapping

2.6.34-stable review patch. If anyone has any objections, please let me know. ------------------ From: Avi Kivity <avi(a)redhat.com> When cr0.wp=0, we may shadow a gpte having u/s=1 and r/w=0 with an spte having u/s=0 and r/w=1. This allows excessive access if the guest sets cr0.wp=1 and accesses through thi... 1 Jul 2010 17:49
