Paul E. McKenney 0051293c53 clocksource: Enable TSC watchdog checking of HPET and PMTMR only when requested
Unconditionally enabling TSC watchdog checking of the HPET and PMTMR
clocksources can degrade latency and performance.  Therefore, provide
a new "watchdog" option to the tsc= boot parameter that opts into such
checking.  Note that tsc=watchdog is overridden by a tsc=nowatchdog
regardless of their relative positions in the list of boot parameters.
