Commit 63753fac67e1 ("x86: Store a per-cpu shadow copy of CR4") in
3.18.y branch introduced a regression on PVH Xen guests.
Please apply 5054daa285be ("x86/xen: Initialize cr4 shadow for 64-bit
PV(H) guests") from mainline to fix this. 3.18.y appears to be the only
affected branch.
Thanks.

Any news on this? Our automated tests of 3.18 are continuing to fail.

+Sasha who I believe is 3.18.y maintainer. I probably should have coped
him on the original message.
