So do you say it's not executed in an atomic?

>From *early* look it seems b43_update_templates is called from
b43_op_beacon_set_tim and b43_op_bss_info_changed, both or them are
mac80211 callbacks. That also should be safe, however I didn't check
if it may conflict with some in-kernel code (still, assuming it's not
atomic code, which I don't know!).
