Changes since v5:

*	rebase on the next branch of powerpc.

*	pull two fix and one testcase patches out, which are already
	sent separately

*	some clean up or code format fixing.


Paul, Peter and Will, thank you for your comments and suggestions in the review
of previous versions. From this version on, This series is against the next
branch of powerpc tree, because most of the code touch arch/powerpc/*.

Sorry if we already discussed this, but did we decide how we were going to
merge this? There's the one patch to generic code and then three powerpc
patches.

We might have "discussed" this ;-) As I proposed this would go to the
powerpc next in this mail:

It'd make most sense for it to go via powerpc I think. Given that the change to
generic code is relatively trivial I'll plan to merge this unless someone
objects.

Also it is pretty late in the -next cycle for something like this. But AFAICS
there are no users of these "atomic*relaxed" variants yet other than arm64 code
and qspinlocks, neither of which are used on powerpc. So adding them should be
pretty harmless.

cheers
