Subject: mm,hugetlb: remove mlock ulimit for SHM_HUGETLB
commit 21a3c273f88c9cbbaf7e ("mm, hugetlb: add thread name and pid to
SHM_HUGETLB mlock rlimit warning") marked this as deprecated in 2012, but
it is not deleted yet.
Mike says he still see that message in log files on occasion, so maybe we
should preserve this warning.
