Commit 4e243b7 (powerpc: Fix "attempt to move .org backwards" error) fixes the
allyesconfig build by moving machine_check_common to a different location.
While this fixes most of the errors, both allmodconfig and allyesconfig still
fail as follows.

arch/powerpc/kernel/exceptions-64s.S:1315: Error: attempt to move .org backwards

Fix by moving machine_check_common after the offending address.

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.

Ok, I think I sorted it out for now. It's a mess and likely to break
again until we do something more drastic like moving everything that's
after 0x8000 to a separate file but for now that will do. Patch on its
way, I'll also shoot it to Linus today along with a few other things.

Great, thanks a lot!
