Hi Alex, could you help to pick up this patch? since v3.14 kernel can
enable numa fault for powerpc.
What bad happens without this patch? We map a page even though it was
declared to get NUMA migrated? What happens next?
Nothing much, we won't be properly accounting the numa access in the
host. What we want to achieve is to convert a guest access of the page to
a host fault so that we can do proper numa access accounting in the
host. This would enable us to migrate the page to the correct numa
node.
Ok, so no breakages, just less performance. I wouldn't consider it
stable material then :).
