Guys, please.

Show some _taste_.

Dammit, stop adding random crap to "native_calibrate_tsc()" and make it
look like total and utter SHIT.

If you want to do that

tsc1 = tsc_read_refs(&ref1, hpet);
..
tsc2 = tsc_read_refs(&ref1, hpet);

around calibration and comparing it, then do it *once*. Do it over the
whole thing. Do it in a function of its own, instead of making this
horrible and unreadable mess.

This patch may be fine as a "let's check if it works" thing, but please
don't send out total SH*T to public lists.

Some _tasted_ in programming, please!
