I think it is very useful.  On such systems you may want to read and
manipulate 64 bit device registers and such, so we need tools to
atomically access these.

Ideally your patch should be split in two: the first would fix ulong,
and the second would add the 64 bit support.

Best regards,

In general, they do what you want, unless you want consistency.
