           Summary: usr/src/sys/arm/at91/at91_machdep.c:261: possible int
                    / long mixup ?
           Product: Base System
           Version: 11.0-CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---

[usr/src/sys/arm/at91/at91_machdep.c:261]: (style) int result is returned as
long value. If the return value is long to avoid loss of information, then you
have loss of information.

Source code is

    return (1 << (cols + rows + banks + bw));

I don't know if this kind of machine is likely to be installed with
> 2Gb RAM, but maybe better code would be

    return (1L << (cols + rows + banks + bw));
