Since RFC this is rebased on Christophe's v3 ppc32 conversion, and has fixed up small details, and then adds some powerpc-wide cleanups at the end.
Tested on qemu only (QEMU e500), which is not ideal for interrupt handling particularly the critical interrupts which I don't know whether it can generate.
