commit d4eed61f85791a8fc4f94ce4fb17997d4ee0eed3
Author: Helge Deller <deller@gmx.de>

    hppa: Add MAP_HUGETLB and MAP_STACK defines [BZ #19285]
    
    The attached patch adds some upstream defines like MAP_HUGETLB and MAP_STACK
    in mman.h for the hppa architecture.
    
    The existing MADV_xxK_PAGES defines were dropped upstream, because they were
    originally added many years ago based on a proposed patch for the Linux kernel
    which was never applied. So, this patch drops those unneeded defines.
