These are now fixed in Linus' tree by:

  6cc22dc08a24 ("revert "mm/memblock: add missing include <linux/bootmem.h>"")

Can you tell we don't test that combination very often :/

I think I'll disable that one, it's been broken more often that not and
I doubt anyone is that motivated to fix sh4 randconfig breakages?

  http://kisskb.ellerman.id.au/kisskb/target/1826/


Relatedly I might move all the randconfig targets from Linus' tree into
a separate "linus-rand" tree, so that they don't pollute the results, as
I've done for linux-next.

That's why you have a special config for it? ;-)

Probably not. Usually I ignore the commonly seen issues.
This one was more uncommon, so I kept it.

Sounds look a good thing.

OK done.

See eg:
  http://kisskb.ellerman.id.au/kisskb/head/14180/


At the moment the "head" page shows the progress/successful for that
head across all branches, so the linus-rand results get counted together
with the linus results which is a bit annoying.

I'm working on a change so that you can view a head *on a branch* so
that you only see the progress/successful for that branch. I'll try and
polish that up and get it pushed RSN.

cheers
