Hi all,

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

In file included from arch/powerpc/include/asm/cmpxchg.h:6,
from arch/powerpc/include/asm/atomic.h:11,
from include/linux/atomic.h:7,
from include/crypto/hash.h:11,
from lib/iov_iter.c:2:
lib/iov_iter.c: In function 'copy_page_to_iter_atomic':
lib/iov_iter.c:546:22: error: implicit declaration of function 'iov_iter_is_pipe'; did you mean 'iov_iter_is_bvec'? [-Werror=implicit-function-declaration]

547 | copied = copy_page_to_iter_pipe(page, offset, bytes, i);
| ^~~~~~~~~~~~~~~~~~~~~~
| copy_page_to_iter

Caused by commit

a53f5dee3448 ("iov_iter: Kill ITER_PIPE")

interacting with commit

c4cf24ce34b7 ("iov_iter: add copy_page_to_iter_atomic()")

from the mm tree.

I have reverted that mm tree commit (and the following two commits)
for today.
