A rereading of this thread reveals the point of the thing was missed.
It's supposed to iterate over online cpus in an given bitmap. It was
meant to replace iterations like:

for_each_cpu(cpu, mask) {
if (!cpu_online(cpu))


for_each_online_cpu(cpu, mask)

Using any_online_cpu() as the starting point repairs it, since that
properly ands mask with cpu_online_map and hands back the first cpu,
though it's only a coincidence it hands back the first such cpu. There
isn't a a first_online_cpu() in the API, that's just effectively what
any_online_cpu() does at the moment.

On the other hand, I just don't care anymore, apart from clarifying
intent so as to counter the implication that all I did back then was
crap gibberish all over the tree. I personally have received zero
recognition or other return on my efforts in this area apart from the
mere fact it was merged. In fact, rather the opposite.
