[Question]CLOCK_EVT_NOTIFY_BROADCAST_EXIT must be called with interrupts disabled?

[Liu, Chuansheng]

Hi,

Just found some comments as below:
In commit 0beefa208bb3a9e581a60125703
+               /*
+                * The switch back from broadcast mode needs to be
+                * called with interrupts disabled.
+                */
+                local_irq_disable();
+                clockevents_notify(CLOCK_EVT_NOTIFY_BROADCAST_EXIT, &cpu);
+                local_irq_enable();


But checked some place in kernel code, it likes below in intel_idle.c:
        local_irq_enable();

        if (!(lapic_timer_reliable_states & (1 << (cstate))))
                clockevents_notify(CLOCK_EVT_NOTIFY_BROADCAST_EXIT, &cpu);
Which enable the irq at first, then calling CLOCK_EVT_NOTIFY_BROADCAST_EXIT.

So not sure _BROAD_EXIT must be called with interrupts disabled? Thanks your 
comments in advance.
