Andrew, All, This small patch insures that cpu_khz is adjusted on cpufreq notifications even when the tsc timesource is not in use. It fixes the mostly cosmetic issue when using the ACPI PM timesource of /proc/cpuinfo not being properly updated when cpu frequency was lowered.
Changelog: A0: Original release A1: Whitespace fix suggested by pavel@suse.cz
Andrew: Please consider for inclusion into your tree for further testing.
thanks -john
