x86: Check tsc available/disabled in the delayed init function The delayed TSC init function does not check whether the system has no TSC or TSC is disabled at the kernel command line, which results in a crash in the work queue based extended calibration due to division by zero because the basic calibration never happened. Add the missing checks and do not touch TSC when not available or disabled. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: John Stultz <johnstul@us.ibm.com>
