As far as I have seen, the _only_ valid gcc-2.8.0-related patch is to
arch/i386/kernel/ioport.c, which is already included in the 2.1.x
release. Including it into a 2.0.x verison is ok.

The other patches I've seen floating around ("bad or insufficiently
tight constraints in asm statements") are gcc-2.8.0 bugs as far as I am
concerned, and will not make it into Linux until the gcc people clearly
document their own bugs as such (thus turning them into features).

I refuse to cater to a buggy compiler, and right now 2.8.0 seems to fall
under the definition.
