[Xen-devel] [RFC PATCH 0/2] x86: fix Xen PV regression caused by NUMA page migration

[David Vrabel <david.vrabel@xxxxxxxxxx>]

This series should properly fix the Xen PV guest regression introduced
by 1667918b6483 (mm: numa: clear numa hinting information on
mprotect).  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
