Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rkuo/linux-hexagon-kernel

Pull Hexagon fixes from Richard Kuo:
 "It's mostly compile fixes and the Hexagon portion of a CPU hotplug
  patch set."

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rkuo/linux-hexagon-kernel:
  hexagon: add missing cpu.h include
  hexagon/CPU hotplug: Add missing call to notify_cpu_starting()
  hexagon:  use renamed tick_nohz_idle_* functions
  Hexagon: misc compile warning/error cleanup due to missing headers
