Subject: linux-next: manual merge of the rr-latest-cpumask tree with the arm
 tree

Hi Rusty,

Today's linux-next merge of the rr-latest-cpumask tree got a conflict in
arch/arm/kernel/smp.c between commit
faa7bc51c11d5bbe440ac04710fd7a3208782000 ("Check whether the TLB
operations need broadcasting on SMP systems") from the arm tree and
commit a29a30f4777dc23679cd588912e0a93f5ab777b0
("cpumask:use-mm_cpumask-arm") from the rr-latest-cpumask tree.

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