[PATCH 0/2] Follow-up on "ARM: Fix dma_alloc_coherent() and friends for NOMMU"

These two patches are folloups on "[PATCH v6 0/7] ARM: Fix
dma_alloc_coherent() and friends for NOMMU" which has been partly
merged in [1]. PATCH 1/2 is done per Christoph's suggestion [2] to
eliminate duplication in dma-noop.c.  PATCH 2/2 is fixup for ARM's dma
operations for NOMMU due to aforementioned change.

@Benjamin, your Tested-by for ARM bits would be very appretiated!

@Christoph, in case you decide to queue PATCH 1/2, can you put it
before "ARM: NOMMU: Introduce dma operations for noMMU", so transition
to the new dma operations won't break bisectability.
