------------------>
Dan Carpenter (1):
      genirq: Fix incorrect unlock in __setup_irq()

Thomas Gleixner (4):
      cris: Fix irq conversion fallout
      cris: Use accessor functions to set IRQ_PER_CPU flag
      genirq: show_interrupts: Check desc->name before printing it blindly
      cris: Use generic show_interrupts()
