In this case plus upcoming staging/rt{286,287,307}0 patches (irrelevant,
they are not used on this machine and the problem happened many times
with vanilla -next kernels in the past)..

After going through mm commits in Linus' tree I think that the bug came
the other way around, from akpm's tree to Linus' tree and then to -next
(page allocator changes seem to match "the suspect's profile")..
