3.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Naoya Horiguchi <n-horigu...@ah.jp.nec.com>
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.
