Subject: [PATCH 08/40] KVM: VMX: When using ept, allow the guest to own cr4.pge
Date: Wed, 10 Feb 2010 19:22:37 +0200 [thread overview]
Message-ID: <1265822589-11155-9-git-send-email-avi@redhat.com> (raw)
In-Reply-To: <1265822589-11155-1-git-send-email-avi@redhat.com>
We make no use of cr4.pge if ept is enabled, but the guest does (to flush
global mappings, as with vmap()), so give the guest ownership of this bit.
