[PATCH] sched_clock() fix

From: Thomas Schlicter

sched_clock() will try to use the TSC even if the system is not using the TSC
as a time source.  It causes bad scheduling decisions and poor interactivity.

The problem was exhibited by the patch which uses ACPI PM as a time source,
but could also happen if the system is using the PIT.
