[PATCH 0/2] x86, apic: APIC timer calibration hook

[Alok Kataria]

Hi,

We need a APIC calibration hook so that we can get the APIC frequency
directly from the hypervisor instead of calibrating it, since
calibration can be error prone in some cases when the kernel is running
virtualized. 

These patches were posted earlier over here
http://lkml.org/lkml/2010/9/20/424 to which Thomas did reply with some
comments. There was no activity of on the thread after some email
exchanges. I will like to post the 2 broken out patches for the 2.6.37
merge window. Please take a look and let me know if you have any
comments. 

1. Preparatory change to add apic timer calibration hook.
2. Adds apic timer calibration hook.

Thanks,
Alok
