linux-next: manual merge of the slab tree with Linus' tree

[Stephen Rothwell]

Hi all,

Today's linux-next merge of the slab tree got a conflict in mm/slub.c
between commit 30106b8ce2cc ("slub: Fix the lockless code on 32-bit
platforms with no 64-bit cmpxchg") from Linus' tree and commit
1759415e630e ("slub: Remove CONFIG_CMPXCHG_LOCAL ifdeffery") from the
slab tree.

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