I've done patches for microblaze, powerpc and x86, and some arch
maintainers have done more. I'd probably do s390 next and see who
else is submitting patches for their architectures in 2.6.32,
then work on those remaining. Feel free to grab any one whose
maintainer you can get hold of.

PIT is interesting, there is also 8253.h in some architectures.
This could use a larger rework, I've started on bits of it
and should probably look which patches are still needed.

It seems that m68k FB_SUN3 support was removed a long time ago,
so this one is really just sparc specific.

This file does not appear to be used at all, we should probably
remove it.

Adrian Bunk killed that file in asm/ back in 2007, he probably crossed
patches with the microblaze architecture.
