That all looks pretty straightforward.  It would be nice to have a
summary of the code-size and stack-usage changes for the whole
patchset.

Can we move `struct alloc_context' into mm/internal.h?

I pity the poor schmuck who has to maintain this patchset for 2 months.
[2/4] already throws a large pile of rejects against page_alloc.c so
can you please refresh/retest/resend?
