Let's work on excp_helper.c and mmu-hash64.c.
For excp_helper.c, ideally everything in there would be tcg related. Either
explicitly as helper_foo() or by being one of the TCGCPUOps functions like
ppc_cpu_exec_interrupt.
For mmu-hash64.c... I guess the easiest thing in the short term is to put big
ifdefs around helper_slbi{a,e,eg}. Or they could be moved to mmu_helper.c,
with slb_lookup declared in mmu-hash64.h.
