eww, how irritating.

find_next_bit() is used in:

- the cpumask code

- Andi's NUMA code

- drivers/atm/lanai.c

- the sched-domains patches in -mm

- and, now, lib/idr.c


the above architectures simply hadn't stumbled across it, but now they
have.

There are fairly generic-looking implementations of find_next_bit() in
alpha, parisc, others.

Could I please ask the relevant arch maintainers to prepare an implementation?

Thanks.
