I am wondering whether we have a wrong usage of a page here? One of the feature
we enabled in the the recent kernel is THP migration
(a0820ff33451aa1a12ec66812e229ac58beb3f24) . But I guess we are not using that
feature. Maybe to isolate this further, can we disable transparent huge page
for all the tests?
