575e321606 [PATCH] powerpc: Make CHRP build again 
This makes CHRP build again, although it's untested because my Pegasos
is currently in pieces.

bbd0abda9c powerpc: Merge 32-bit CHRP support. 
SMP still needs more work but UP gets as far as starting userspace
at least.  This uses the 64-bit-style code for spinning up the cpus.
