It's a combination of changes - my initial changes for fixing the ARMv7
DMA support went in last night, but were based on a tree older than
Catalin's changes, which had already been committed.

My test build didn't catch any of these - it's the usual problem that
there is no way to adequately build-test the ARM kernel in a reasonable
time anymore.
