The difference would appear to be the number of remote TLB

paths.

So either there's been a massive increase in the number of IPIs
being sent, or the cost per IPI have greatly increased. Either way,
the result is a pretty significant performance degradatation.

That warning was put there on purpose to tell us that there's a

not really see a reason to change GFP_NOFS vs.
OOM killer semantic.
So, really, what we want is something like:
#define __GFP_USE_LOWMEM_RESERVE__GFP_HIGH
So that it documents the code that is using it effectively and we
can find them easily with cscope/grep?
