Ok, bad news - I've been hit by kswapd0 loop again - my kernel git commit cc19528bd3084c3c2d870b31a3578da8c69952f3 again shown kswapd0 for couple minutes on CPU. It seemed to go instantly away when I've drop caches (echo 3 >/proc/sys/vm/drop_cache) (After that I've had over 1G free memory)Any chance you could retry with this patch on top?
It does not apply to -next :/. Should I try anything else?

What seems to be triggering condition on my machine - running laptop for some days - and having Thunderbird reaching 0.8G (I guess they must keep all my news messages in memory to consume that size) and Firefox 1.3GB of consumed memory (assuming massive leaking with combination of flash)
Similar here, 5 days of uptime (suspend/resumes in between). FF 900M, TB 250M, java 1.1G, kvm 550M, X 400M, cache 1.5G out of 6G total mem.
