3.8-stable review patch. If anyone has any objections, please let me know.
------------------ From: Naoya Horiguchi <[email protected]> commit 23d9e482136e31c9d287633a6e473daa172767c4 upstream. Documentation/filesystems/proc.txt says about coredump_filter bitmask, Note bit 0-4 doesn't effect any hugetlb memory. hugetlb memory are only effected by bit 5-6. However current code can go into the subsequent flag checks of bit 0-4 for vma(VM_HUGETLB). So this patch inserts 'return' and makes it work as written in the document.
