Hi folks,
kvmclock currently falls apart on machines without constant tsc.
This patch fixes it. Changes:
* keep tsc frequency in a per-cpu variable.
* handle kvmclock update using a new request flag, thus checking
whenever we need an update each time we enter guest context.
* use a cpufreq notifier to track frequency changes and force
kvmclock updates.
* send ipis to kick cpu out of guest context if needed to make
sure the guest doesn't see stale values.
cheers,
Gerd
ACK for 2.6.29 (but please fix the whitespace breakage).
Whitespace fixed version attached.
Applied, thanks (together with a revert of the commit that disables
kvmclock on !constant_tsc).
