[Xen-devel] [PATCH 0/4] x86: reduce errors in frequency calculations / unrelated cleanup

While looking into ways to increase the accuracy of the clock speeds
we work with (in particular by possibly obtaining information from
hardware rather than measuring), I first of all noticed some
avoidable rounding errors in some of our calculations. That's what
patches 2 and 3 are intended to deal with. Patch 1 is preparatory
cleanup, while patch 4 simply addresses something I got annoyed by
yet another time while doing this investigation.

1: APIC: adjust types and comments in calibrate_APIC_clock()
2: time: reduce rounding errors in calculations
3: APIC: reduce rounding errors in calculations
4: APIC: restrict certain messages to BSP
