Include backport of vmware stable TSC patchset

[Stefan Bader]

This is a tracking bug for the mailing list request to include backported vmware patches.

I had to give you a heads up on some patches that we would want you to
consider for your ubuntu hardy and intrepid tree.
These patches fix some of the TSC related bugs which occur only in a
virtualized environment. The reason they are important for VMware is
because we rely on TSC as the primary clocksource for timekeeping rather
than a paravirtualized clocksource.

So these patches are pretty important for correct timekeeping under
VMware.

Can you please pick these patches for the next kernel update/release.
They are in the x86 tree right now and should be merged during the
2.6.29 merge cycle.

Fixes have been committed to Hardy. One additional patch added to import those changes into Xen specific header files.

Hi Stefan,

I would like to test this on our ESX setup as we often see the 'Clocksource tsc unstable' warnings on these machines. Do you have a test case to reliably repeat the issue? We get the warning sporadically without any obvious pattern which makes testing the -proposed packages a little tricky..

Thanks, Paul.

[Stefan Bader (smb)]

As I don't have a real good environment for this, I never saw this myself. The
descriptions of the bug sound like it could happen more often when the host is
very busy (probably the guest workload should not be to high but might not
matter much). So the guest process is not scheduled for a longer period of time
by the host...
