Hi Paul,

After merging the rcu tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

fs/binfmt_misc.c: In function 'create_entry':
fs/binfmt_misc.c:314:2: error: implicit declaration of function '_copy_from_user' [-Werror=implicit-function-declaration]

Caused by commit d17faaa53e2e ("fs: Silence bogus copy_to_user() build
errors"). _copy_from_user() appears to only exist for the x86 and tile
architectures ...

I have used the rcu tree from next-20120413 for today.
