Well, it might not eve be necessary. In the patch I sent you, it pointed
the finger at commit 5f8dcc21211a3d4e3a7a5ca366b469fb88117f61 being the
problem in that case. I believe your problem is a variation of the
slowdown-in-swapping problem except in your case it manifests as
GFP_ATOMIC allocations failing.

If the fix does not help you, then I'll take a fresh look at the other
commits with your particular problem in mind.
