You can also go totally mad and generate the whole function (both -s and

Please don't (unless you keep the function names intact), it makes
finding the function with grep almost impossible ...

Also - any opinion on whether the same re-factoring of the asm-generic
versions should be undertaken? I'm not looking to bite off more than I
can chew, but I don't know if it's frowned upon to make powerpc-only
extensions to the API. And if you think an asm-generic patch makes
sense, could that be taken via linuxppc-dev too or does it need to go
elsewhere?

I'm not people care -that- much :-) You can always try and post it to
lkml (maybe linux-arch too) and see what comes back... but let's finish
the powerpc variant first :-)

Also, we have an asm-generic maintainer now ...
