[PATCH 0/9] powerpc: MMU cleanup and propare for new Book3-E

[Benjamin Herrenschmidt]

This series of patches does some ground work to make 32 and 64-bit
page table and PTE access slightly more common and to facilitate
the addition of a new MMU type (Book3-E version 2.06 and later)
for which I'd like to be able to use the same definitions for both
32 and 64-bit implementations.

There should be little actual change to the compiled code, when there
is I should have mentioned it or separated the patch, unless I missed
something, it's mostly a matter of moving things around.

Note: some of the patches were already posted separately, those
shouldn't have changed since their were last sent to the list but
I'm resending the whole lot here for consistency.
