Ok, this patch set builds on top of the variable PAGE_OFFSET
patches.

First we move to 8MB huge pages.  The chips don't really have
8MB page support, but we fabricate such a thing using 4MB
PTEs.

Next we move to 64-bit pmd_t and pgd_t entries, which is the
most trivial of the changes here.

Finally, we encode huge PMDs using the plain PTE encoding of
huge pages.   All of the ugly huge PMD --> PTE translation
code disappears, and the TLB miss path is smaller and faster.

I just got this stuff fully working so caveat emptor :-)
