Peter Zijlstra 2406e3b166 perf/x86/intel, watchdog/core: Sanitize PMU HT bug workaround
The lockup_detector_suspend/resume() interface is broken in several ways
especially as it results in recursive locking of the CPU hotplug lock.

Use the new stop/restart interface in the perf NMI watchdog to temporarily
disable and reenable the already active watchdog events. That's enough to
handle it.
