f3d3444572 powerpc/mm: Fix typo in PTRS_PER_PUD
PTRS_PER_PUD should be based on PUD_INDEX_SIZE, not PMD_INDEX_SIZE.  We
got away with it because PUD and PMD had the same index size, but this is
no longer true with Aneesh's patchset to support a 46-bit user effective
address space.

c605782b1c powerpc/mm: Split the various pgtable-* headers based on MMU type
This patch moves the definition of the PTE format for each MMU type
to separate files instead of all in one file. This improves overall
maintainability and will make it easier to add new types.

On 64-bit, additionally, I've separated the headers relative to the
format of the page table tree (3 vs. 4 levels for 64K vs 4K pages)
from the headers specific to the PTE format for hash based processors,
this will make it easier to add support for Book3 "E" 64-bit
implementations.

There are still some type-related ifdef's in the generic headers,
we might remove them in the long run, but this patch shouldn't result
in any code change, -hopefully- just definitions being moved around.
