Subject: [PATCH 0/2] Add hugetlbfs support to memfd_create()

This is a resend of the patch sent in the RFC:
http://lkml.kernel.org/r/1502149672-7759-1-git-send-email-mike.kravetz@oracle.com

It addresses the issues with the commit message raised by Michal Hocko.
Only the commit message is modified, the code from the RFC patch is the
same.

In addition, a new patch is included to modify the memfd selftest.  The
modifications allow basic functionality testing of memfd_create with
hugetlbfs.
