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

[Stephen Rothwell]

Hi Andrew,

Today's linux-next merge of the akpm-current tree got a conflict in
kernel/smp.c between commit f44310b98ddb ("smp: Fix SMP function call
empty cpu mask race") from Linus' tree and commit "smp: make
smp_call_function_many() use logic similar to smp_call_function_single()"
from the akpm-current tree.

I fixed it up (I think - see below) and can carry the fix as necessary
(no action is required).
