This patch should be split up.

Octeon, PowerTV, and IP32 are all different architectures.  They should 
be in their own patches.

The two math-emu parts could probably go together.

cpu-probe seems like its own thing.

This brings us to the larger question:  This is just code churn.  Is it 
even worthwhile?
