Subject: [RFC PATCH 0/2] x86: fix Xen PV regression caused by NUMA page migration
Date: Fri, 21 Mar 2014 18:18:20 +0000 [thread overview]
Message-ID: <1395425902-29817-1-git-send-email-david.vrabel@citrix.com> (raw)
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
