This keeps the code together and will simplify compiling the code

And this is where things take a turn in the direction I just can't get on
with - I'm looking at the final result and the twisty maze of little
disjoint helpers all overlapping each other in functionality is really
difficult to follow. And I would *much* rather have things rely on
compile-time constant optimisation than spend the future having to fix the
#ifdefed parts for arm64 whenever x86-centric changes fail to test them.
Can you draft up a patch on top of my series to show me what you
want? I can take care of finishing it up and moving the changes
into the right patches in the series.
Any chance to make some progress on this? Or at least a better
description of what you want?
OK, I'm still looking at mmap and get_sgtable, but for now I've pushed
out a partial branch that consolidates alloc and free in a way which
makes sense to me:
git://linux-arm.org/linux-rm dma/rework
Please let me know what you think.
Robin.
