Ok. I just saw ubifs implementing its own set_bit() functions and
considered that the wrong place for such functions to live in. ext2
seems to do the same things, also minix. Platforms which want to
enable support for these filesystems have to do an evil #define to
map ext2_set_bit() to the platform specific version. Which is all
bogus, you might agree. And because of that situation, ubifs can't
currently build for anything else than ppc
(according to 'git grep -w fls include/asm*').

Hence I thought it might be a good idea (or at least a good start
thereof) to put the functions where I believe they belong to - a
'generic' place.

Anyway - applying the first patch of this series would at least prevent
others from being mislead by dead and wrong code.
