    [PATCH] hugetlb: fix MAP_FIXED handling · cf9b6e7a

    ia64 reserves virtual address region 4 (any address which starts with 0x4)
    for huge pages.
    
    Apparently, for hardware reasons, we do not wish to allow mappings with
    other page sizes to appear in that region.
    
    This patch prevents the user from being able to place regular MAP_FIXED
    mappings into region 4 on ia64.  It is a no-op for ia32.
