FYI, we noticed a +4218 bytes kernel size regression due to commit:
commit: 865e23483ff94043ca26eba00422fe2b245d3dfc (linux-next)
https://github.com/hnaz/linux-mm master
Details as below (size data is obtained by `nm --size-sort vmlinux`):

This commit in this tree is a snapshot of the entire linux-next patch
stack. Bisecting and flagging that particular commit to this
particular CC list is probably not useful.
Andrew would know best, but to analyze/bisect the MM tree for
regressions, it'd probably be best to only do the individual commits
between the `origin' (the Linus base) and `linux-next' commits.
(There are also individual mm commits post linux-next{,-rejects}, but
they include debug patches and private mm tree things that may not now
or may never be slated for upstream inclusion, so probably best to
skip those?)

The same regression should be present in Stephen's linux-next tree, so
bisect that?
