Benjamin Herrenschmidt 32a74949b7 powerpc/mm: Add support for SPARSEMEM_VMEMMAP on 64-bit Book3E 
The base TLB support didn't include support for SPARSEMEM_VMEMMAP, though
we did carve out some virtual space for it, the necessary support code
wasn't there. This implements it by using 16M pages for now, though the
page size could easily be changed at runtime if necessary.
