[PATCH] powerpc: Fix 64k pages on non-partitioned machines
The page size encoding passed to tlbie is incorrect for new-style large pages. This fixes it. This doesn't affect anything on older machines because mmu_psize_defs[psize].penc (the page size encoding) is 0 for 4k and 16M pages (the two are distinguished by a separate "is a large page" bit).
