This is fine now in master after Andrew's revert, but the problematic
patch is still being picked up in linux-next somehow. This breaks MIPS
builds from linux-next, and presumably the ia64 build too.
I'm not sure I understand how it's picked up - next-20180621 appears to
based atop 1abd8a8f39cd:
$ git show next-20180621:Next/SHA1s | grep -E '^origin\s'
origin 1abd8a8f39cd9a2925149000056494523c85643a
There we have the Andrew's revert:
$ git log --pretty=oneline -n5 1abd8a8f39cd mm/memblock.c
6cc22dc08a247b7b4a173e4561e39705a557d300 revert "mm/memblock: add missing include <linux/bootmem.h>"

Yet the revert doesn't show up at all in next-20180621..?

I was expecting to see the original commit, then the revert, then
perhaps a re-application of it but instead it looks like the commits
from master are missing entirely after 25cf23d7a957 ("mm/memblock: print
memblock_remove"). Maybe I'm missing something about the way the merges
for linux-next are done..?
In any case, could we get the problematic patch removed from linux-next?
Thanks,
Paul
