The previous fix a9c8e4beeeb6 (xen: properly account for _PAGE_NUMA during xen pte translations) breaks save/restore (migration) and needs to be reverted. I've only given this series a minimal amount of testing and would appreciate testing by someone who experienced/reproduced the original regression. David
