The current design of hrtimers migrates the pinned timers to a different CPU upon its hotplug. However, perf-core needs to maintain the mux-hrtimers on a per CPU basis. That is, each hrtimer carries the context for that particular CPU and would lose this context if it gets migrated to a different CPU. As a result, cancel the hrtimer for the CPU that's about to go down and restart it (if required) when the perf-events are being created.
