How is this static call related to the timer vector? It just works with
the conditional callback. apic_update_vector() is not used in a
hotpath.

Even if there is a valid reason for the static call, why is this not
part of the patch, which adds the update_vector() callback?

It's well documented that you should not do random unrelated things in
patches.

You really try hard to make review a pain.

Thanks,
