... plus some tidying (or so I hope). Only the 1st patch was submitted
so far (i.e. as v1), all others are new.

1: time: further improve TSC / CPU freq calibration accuracy
2: APIC: calibrate against platform timer when possible
3: APIC: skip unnecessary parts of __setup_APIC_LVTT()
4: APIC: make connections between seemingly arbitrary numbers
