Gautham R Shenoy d2b20b1154 Add irq protection in the percpu-counters cpu-hotplug-callback path ...

Some of the per-cpu counters and thus their locks are accessed from IRQ
contexts.  This can cause a deadlock if it interrupts a cpu-offline thread
which is transferring a dead-cpu's counts to the global counter.

Add appropriate IRQ protection in the cpu-hotplug callback path.
