Hi all,
After merging the akpm-current tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
mm/shmem.c:2365:12: warning: 'enum mcopy_atomic_mode' declared inside parameter list will not be visible outside of this definition or declaration

Caused by commit
3407bec05d6d ("userfaultfd: support minor fault handling for shmem")
# CONFIG_USERFAULTFD is not set
I have reverted that commit (and the following 4 as well).
