The patch titled
kvm: Fix mmu going crazy of guest sets cr0.wp == 0
has been removed from the -mm tree. Its filename was
kvm-fix-mmu-going-crazy-of-guest-sets-cr0wp-==-0.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: kvm: Fix mmu going crazy of guest sets cr0.wp == 0
From: Avi Kivity <avi@xxxxxxxxxxxx>
The kvm mmu relies on cr0.wp being set even if the guest does not set it. The
vmx code correctly forces cr0.wp at all times, the svm code does not, so it
can't boot solaris without this patch.
