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.
