Merge branches 'irq-fixes-for-linus' and 'sched-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip 

* 'irq-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
  genirq: Fix incorrect unlock in __setup_irq()
  cris: Use generic show_interrupts()
  genirq: show_interrupts: Check desc->name before printing it blindly
  cris: Use accessor functions to set IRQ_PER_CPU flag
  cris: Fix irq conversion fallout

* 'sched-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
  sched, kernel-doc: Fix runqueue_is_locked() description
