Subject: [PATCH] generic-ipi: cleanup for
 generic_smp_call_function_interrupt()

Use smp_processor_id() instead of get_cpu() and put_cpu() in
generic_smp_call_function_interrupt(), It's no need to disable preempt,
because we must call generic_smp_call_function_interrupt() with interrupts
disabled.
