Nitin Gupta 70f3c8b7c2 sparc64: Fix page table walk for PUD hugepages
For a PUD hugepage entry, we need to propagate bits [32:22]
from virtual address to resolve at 4M granularity. However,
the current code was incorrectly propagating bits [29:19].
This bug can cause incorrect data to be returned for pages
backed with 16G hugepages.
