Conflicts:
	arch/arm/mach-shmobile/board-ap4evb.c

This moves the addition of init_consistent_dma_size() from the board
files into the common sh7372_map_io() functions where all the other
contents of the board specific map_io calls have gone.

5cd9eb2736 Merge branch 'renesas/fixes' into renesas/soc
The fixes branch was merged into mainline just after v3.3-rc7,
I'm merging it into this branch to fix up a nontrivial merge
conflict. Unfortunately this means that we are now based on
a commit between -rc releases, which we normally try to avoid.

Commit 171c067 ("ARM: EXYNOS: add support uart for EXYNOS4 and
