Subject: [PATCH 0/3] Fix cr0.wp=0 emulation
Date: Thu, 27 May 2010 14:50:03 +0300 [thread overview]
Message-ID: <1274961006-19413-1-git-send-email-avi@redhat.com> (raw)
Xiao didn't find the nice cr0.wp=0 trick because it wasn't there, removed
accidentally by b70ccb0b3fd. Restore the trick and document it.
Avi Kivity (3):
KVM: MMU: Allow spte.w=1 for gpte.w=0 and cr0.wp=0 only in shadow
mode
KVM: MMU: Remove user access when allowing kernel access to gpte.w=0
page
KVM: MMU: Document cr0.wp emulation
