timer: Fix hotplug regression
The recent timer wheel rework removed the get/put_cpu_var() pair in the hotplug migration code, which results in: BUG: using smp_processor_id() in preemptible [00000000] code: hib.sh/2845 ... [<ffffffff810d4fa3>] timer_cpu_notify+0x53/0x12 That hunk is a leftover from an earlier iteration and went unnoticed so far. Restore the previous code which was obviously correct. Fixes: 0eeda71bc30d 'timer: Replace timer base by a cpu index' Reported-and_tested-by: Borislav Petkov <bp@alien8.de> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
