Date: Thu, 5 Mar 2009 13:12:33 +0100 From: Joerg Roedel <joerg.roedel@....com> To: Avi Kivity <avi@...hat.com>, Marcelo Tosatti <mtosatti@...hat.com> CC: kvm@...r.kernel.org, linux-kernel@...r.kernel.org, Joerg Roedel <joerg.roedel@....com> Subject: [PATCH 6/6] kvm/x86/mmu: include PT_PAGE_SIZE_MASK in PT64_PERM_MASK We also need to do a remote tlb flush if the PSE bit changes. The pte_pfn should also change if this bit changes but we can't rely on that. So check this bit too to be on the save side.
