Hi all,
After merging the final tree, today's linux-next build (sparc32 defconfig)
failed like this:

Caused by commit 41aed1ec2e09 ("lru: add an element to a memcg list")
from the akpm tree. This patch added an include of linux/mm.h to
linux/memcontrol.h, but that was unneeded as the rest of the patch only
added dependencies on pointers to struct page and struct mem_cgroup -
both of which are already declared in this header.
I have applied the following patch for today:
