disable_irq() after request_irq() still has a time gap in which
interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will

This patchset added IRQF_NO_AUTOEN for request_irq() and converted
drivers/input to this new API.
Other drivers will be handled afterwards.

Right now, irq core supports requesting irq with IRQF_NO_AUTOEN, this means
the driver doesn't need to call irq_set_status_flags any more.

mask is built in build_balance_mask() by for_each_cpu(i, sg_span), so
it must be a subset of sched_group_span(sg). Though cpumask_first_and
doesn't lead to a wrong result of balance cpu, it is pointless to do
cpumask_and again.
