Re: RFC: powerpc: Start splitting up mmu.h by MMU type

David Gibson writes:

This patch makes a start to sorting out the tangled mess of MMU
related header files in asm-powerpc, and weaning arch/powerpc off the
remaining asm-ppc headers it uses.

Good...

Specifically it splits the ppc64 specific (or more strictly, the
64-bit hash table specific) parts of asm-powerpc/mmu.h into its own
file, asm-powerpc/mmu-hash64/mmu.h.  Similarly, PowerPC 44x
definitions are taken from asm-ppc/mmu.h, trimmed down for use in
arch/powerpc and place in their own file, asm-powerpc/mmu-44x/mmu.h.

Why do we want to create a directory per mmu type?  What other files
would go in there?
