Unrelated to the camelcase conversion, this casting of
a (u32 *) to an (unsigned long *) to set a bit seems
like a bad idea and an error waiting to happen.

Does it really need to be atomic?

Perhaps it'd be better to write something like:

monitorpage->TriggerGroup[channel->MonitorGroup].Pending |=
(1 << channel->MonitorBit);

Maybe like the other 2 uses of set_bit in hv, it
should be set_bit(channel->MonitorBit & 31, ...
