Oops I thought it was typo on your prev email so I didn't answer
assuming you would test 39-rc like I suggested in my prev email, I
really meant 2.6.39-rc3.
The fix I refer to is d527caf22e48480b102c7c6ee5b9ba12170148f7 and
it's included in >= 2.6.39-rc1. 38-rc3 has THP but not this
changeset. We tried to push it for 38 final but it was a bit late so
it got merged immediately in 39-rc1 to stay on the safe side (it's
only a performance issue and the other longstanding irq/sched latency
issues in compaction that got fixed in 39-rc1 where actually more
relevant than the compaction-kswapd removal).
