Hi,

yeah, actually I was on the verge of completely removing that calibrate_cpu code since maybe 99% of the systems out there should have a TSC counting with the P0 rate so the issue becomes moot and no need for fixing. But according to Murphy, there'll be this one system which needs it and thus we have to keep it, unfortunately.
Anyway, I'll keep you posted.
Thanks.
