It depends on what platform you want to look at, powerpc64, powerpc32 classic
and powerpc32 book E are very different, but you'll see that in the code.

arch/powerpc/mm/hash*
arch/powerpc/mm/pgtable*
arch/powerpc/mm/mem.c
arch/powerpc/mm/ppc_mmu_32.c
arch/powerpc/mm/slb*
arch/powerpc/mm/stab.c
arch/powerpc/mm/tlb*
include/asm-powerpc/mmu*
include/asm-powerpc/pgalloc*
include/asm-powerpc/pgtable*

That should cover all you need to know.
