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. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
