Satya Durga Srinivasu Prabhala 61d1f2eb9b hrtimer: fix issue during core isolation ... During core isolation, while migrating hrtimers to one of online CPUs, below issue is being observed due to commit 5da7016046 ("hrtimer: Implement support for softirq based hrtimers") which started to enable local irqs. Fix it by moving local_bh_disable/enable calls to hotplug path only.
