linux-next: manual merge of the percpu tree with the slab tree

[Stephen Rothwell]

Hi all,

Today's linux-next merge of the percpu tree got a conflict in mm/slab.c
between commit ce79ddc8e2376a9a93c7d42daf89bfcbb9187e62 ("SLAB: Fix
lockdep annotations for CPU hotplug") from the slab tree and commit
1871e52c76dd95895caeb772f845a1718dcbcd75 ("percpu: make percpu symbols
under kernel/ and mm/ unique") from the percpu tree.

Just context changes.  I fixed it up (see below) and can carry the fix as
necessary.

The fixup looks good to me. Thanks, Stephen!
