Or make the counter s64? so that it stays 64 bit on all arches?
OR
why not change the global per-cpu counter type to unsigned long (as we
discussed earlier), so we don't need the extra "ul" flags and interfaces,
and all arches get a standard unsigned long return type? We could also
do away with percpu_read_positive then no? The applications for per-cpu
counters is going to be upcounters always methinks...
Thanks,
