Can you add 2M and 1G #defines also so that i can drop the patch from my series and pick this ? -aneesh

This just adds user space exported ABI definitions for both 16MB and 16GB non default huge page sizes to be used with mmap() system call. Signed-off-by: Anshuman Khandual <khandual@linux.vnet.ibm.com> --- These defined values will be used along with MAP_HUGETLB while calling mmap() system call if the desired HugeTLB page size is not the default one.
