It took me a bit of time to understand why we can reduce the patch to
just MIPS definitions. Indeed, in the patch, there are some m68k and
PA-RISC definitions which we don't really care about since we don't
support those architectures. However, the SPARC definitions we do care
about. But in fact, they have been merged upstream. It would have been
good to add such explanations in the commit log, to ease review. I've
adjusted the commit log to make this explicit.

Another comment is that the title should always be:

	<package>: <what happens>

i.e something like:

	libaio: bump to version 0.3.110

Vicente, can you work with libaio upstream to get the MIPS specific
definitions merged? Maybe this should also be enabled on
mips64/mips64el.

I've changed this to keep the alphabetic ordering, and applied your
patch to our next branch.

Thanks!
