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

[Stephen Rothwell <sfr@canb.auug.org.au>]

Hi all,

Today's linux-next merge of the arm-soc tree got a conflict in
arch/arm/mach-exynos/dma.c between commit 20df8641cc1a ("ARM: amba:
samsung: get rid of NO_IRQ initializers") from the arm tree and commits
2b7841baf665 ("ARM: EXYNOS: Enable MDMA driver") and  bf2f272ad446 ("ARM:
EXYNOS: Support DMA for EXYNOS4X12 SoCs") from the arm-soc tree.

I fixed it up (there may be more required - see below) and can carry the
fix as necessary.

Cheers,
