Submit upstream

Having a /sys/devices/system/cpu/cpu0/tsc_freq_khz seems to be generally useful.

Do you plan to submit a patch with this functionality to the LKML?

I agree it would be useful but I think the current code is not ready: it is missing some important parts like checking for existence of CPU0 (not guaranteed with hotplug), and verifying that the value makes sense before exporting it (in the case of a tsc that doesn't sync across cores, for instance).

I was hoping that Google could upstream whatever they have, it is probably much better than my version :).

This is nice - much better than userspace calibration code. Thanks
