[PATCH 3/4] sparc64: Fix gup_huge_pmd

The function assumes that each PMD points to head of a huge page. This is not correct as a PMD can point to start of any 8M region with a, say 256M, hugepage. The fix ensures that it points to the correct head of any PMD huge page. Signed-off-by: Nitin Gupta ---
