FP_DECL_EX is already used, so ret is redundant.
And FP_SET_EXCEPTION will add status into return value.

The math emulation code is centered around a set of generic macros that
provide the core of the emulation that are shared by the various
architectures and other projects (like glibc). Each arch implements its
own sfp-machine.h to specific various arch specific details.
For historic reasons that are now lost the powerpc math-emu code had
its own version of the common headers. This moves us to using the
kernel generic version and thus getting fixes when those are updated.
Also cleaned up exception/error reporting from the FP emulation functions.

Towards the goal of having arch/powerpc not build anything over in arch/ppc
move math-emu over. Also, killed some references to arch/ppc/ in the
arch/powerpc Makefile which should belong in drivers/ when the particular
sub-arch's move over to arch/powerpc.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
