This suffers from the same problem as previous attempts, on some of my
test configs I get:

arch/powerpc/kernel/head_64.o:(__ftr_alt_97+0xb0): relocation truncated to fit: R_PPC64_REL14 against `.text'+1c90
make[1]: *** [vmlinux] Error 1
make: *** [sub-make] Error 2

IE, it breaks currently working configs.

So we need to move more things around and I haven't had a chance to
sort it out.

Cheers,
Ben.
