Hm...what about Documentation/hpet.txt, where it is written:

The kernel API has three interfaces exported from the driver:

	hpet_register(struct hpet_task *tp, int periodic)
	hpet_unregister(struct hpet_task *tp)
	hpet_control(struct hpet_task *tp, unsigned int cmd, unsigned long arg)

Maybe someone could update that file too, to help anyone who wants to
learn about hpet ( hpet_register(...) and hpet_control(...) don't even
exist anymore in the kernel)
