commit 99192daf72164738707cce5137b8648c098e2a64
Author: Anshuman Khandual <khandual@linux.vnet.ibm.com>
Date:   Fri Apr 7 09:25:39 2017 +0530

    powerpc/hugetlb: Add ABI defines for supported HugeTLB page sizes
    
    Add user space exported API definitions for 512KB, 1MB, 2MB, 8MB, 16MB,
    1GB, 16GB non default huge page sizes to be used with mmap() system
    call.
    
    Signed-off-by: Anshuman Khandual <khandual@linux.vnet.ibm.com>
    [mpe: Reword the comment to emphasise that these are only needed to use
     the non-default huge page size, and updated the change log.]
