Subject: linux-next: manual merge of the arm tree with the arm-current tree

Hi Russell,

Today's linux-next merge of the arm tree got a conflict in
arch/arm/mm/mmu.c between commit f1a2481c0ad3aebd94d11b317c488deaadc25002
("ARM: 6407/1: mmu: Setup MT_MEMORY and MT_MEMORY_NONCACHED L1 entries")
from the arm-current tree and commit
dc966984f44f16b8bb6b0644e501c7c2163ead69 ("ARM: Allow SMP kernels to boot
on UP systems") from the arm tree.

I fixed it up (see below) and can carry the fix for a while.
