All files get copyright boilerplate.
yeah, I didn't expect this file to stick around, though, as the last
time we made a stub file, it ended up not being used, so I decided to go
the quick route

+hwaddr ppc_cpu_get_phys_page_debug(CPUState *cs, vaddr addr)

This is used by gdbstub.
If there's a way for kvm to convert a virtual address to a physical
address using the hardware, then use that. I suspect there is not.
Otherwise, you have to keep all of the mmu page table walking stuff
for kvm as well as tcg. Which probably means that all of the other
stuff that you're stubbing out is used or usable as well.
ah, this probably means we'll need to compile mmu_helper.c too... that
was something we were hoping to avoid, because of the sheer size.
