[Intrepid] SRU Include backport of vmware stable TSC patchset

[Stefan Bader]

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/319945

SRU justification:

Impact: Timekeeping relies on TSC which is always stable in the virtualized 
vmware environment. But the code to detect TSC as a stable clocksource fails. 
Together with the possibility of the acpi_pm timer to wrap around while not 
scheduled, this can cause several second clocksews.

Fix: This patch series was backported to Intrepid and will get included with 
2.6.29rc3. The changes do not look like they could cause regressions. However 
they require an ABI bump for adding elements to per_cpu__cpu_info and 
boot_cpu_data.

Stefan

Tim, I already took the liberty of adding your ack based on your previous 
comments. The ABI bump would fall together with the 2.6.27.12 update which also 
requires one.
