Since updating my ARAnym VMs from 3.12.16 to 3.13.11 I see kswapd0

rises to about 30-50% CPU even though RAM shouldn't be anywhere near
depleted (768GB, a gcc bootstrap running in a screen session).
kswapd0 tends to stay this way until I drop caches, but doing that
doesn't always fix it. I also sometimes see ksoftirqd/0 consume
5-30% CPU.
Reverting to 3.12.16 completely eliminates these problems.
Any chance to bisect it?
I haven't tested 3.14 or 3.15-rc yet.
Would be good to know, though, as it may have been fixed.
However, as v3.13.11 is the most recent stable version of v3.13, this may be
an elsewhere unknown and thus unfixed issue.
