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?

Ok, I'm running now b69f0859dc8e633c5d8c06845811588fe17e68b3 (-rc8)
with your patch. I'll be able to give some feedback after couple
days (if I keep my machine running without reboot - since before
I had occasional problems with ACPI now resolved.
(https://bugzilla.kernel.org/show_bug.cgi?id=51071)
(patch not yet in -rc8)
I'm also using this extra patch: https://patchwork.kernel.org/patch/1792531/
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)
