Drop bogus definitions of ranges for ARCH_FORCE_MAX_ORDER and leave it a simple integer with sensible defaults. Users that *really* need to change the value of ARCH_FORCE_MAX_ORDER will be able to do so but they won't be mislead by the bogus ranges. Signed-off-by: Mike Rapoport (IBM) Acked-by: Kirill A.
