Applied, thanks! Do we still want the __GFP_REPEAT patch from Konstantin

OTOH, I'm slightly worried that it might mask a real problem
with GFP_KERNEL not being aggressive enough. Mel?
I think that's already been demonstrated here, yes. It's just waiting
for another obscure workload to trigger it.
I Agree, __GFP_REPEAT doesn't fix the problem completely. So, some more detailed investigation required.
My case is not very honest, because my kernel has slightly different memory controller, and it has bugs for sure.
