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

Hi Arnd,

[I have a feeling that I may have reported this previously]

Today's linux-next merge of the arm-soc tree got a conflict in
arch/arm/mm/dma-mapping.c between commit e73fc88e19d7 ("ARM: 7059/1:
LPAE: Use PMD_(SHIFT|SIZE|MASK) instead of PGDIR_*") from the arm tree
and commit 99d1717dd7fe ("ARM: Add init_consistent_dma_size()") from the
arm-soc tree.

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