Stephen, can you add this branch to the linux-next tree?

I see there are still comments coming in, but at some point this has
to just be considered good enough that any further changes can be addressed
with patches on top rather than rebasing.

I was expecting that you'd base this on just the spinlock changes from Palmer's
tree that are part of the asm-generic tree rather than all of what I have.

Can you rebase it once more? If there are conflicts against the h8300 removal
series that is also in asm-generic, leaving it on top of that may be
easier though.
