Attilio Rao 306c0c6ea0 Improving the clocks auto-tunning by firstly checking if the atrtc may be ... correctly initialized and just then assign to softclock/profclock. Right now, some atrtc seems reporting strange diagnostic error* making the current pattern bogus. In order to do that cleanly, lapic_setup_clock(), on both ia32 and amd64, now accepts as arguments the desired sources to handle, and returns the actual ones (LAPIC_CLOCK_NONE is forbidden because otherwise there is no meaning in calling such function). This allows to bring out into commont x86 code the handling part for machdep.lapic_allclocks tunable, which is retained.
