[SPARC64]: Fix 2 bugs in huge page support.
1) huge_pte_offset() did not check the page table hierarchy elements as being empty correctly, resulting in an OOPS 2) Need platform specific hugetlb_get_unmapped_area() to handle the top-down vs. bottom-up address space allocation strategies. Signed-off-by: David S. Miller <davem@davemloft.net>
