The changelog comment will change to:

There are some feedbacks from irqchip, and we need to adjust "smp.c & smp.h"
to match the csky_mptimer modification.
 - Move IPI_IRQ define into drivers/irqchip/csky_mpintc.c, because it's a
   interrupt controller specific.
 - Bugfix request_irq with IPI_IRQ, we must use irq_mapping return value not
   directly use IPI_IRQ. The modification also involves csky_mpintc.
