Merge branch 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus

* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus:
  [MIPS] time: Move R4000 clockevent device code to separate configurable file
  [MIPS] time: Delete dead cycles_per_jiffy, mips_timer_ack and null_timer_ack
  [MIPS] IP32: Retire use of plat_timer_setup.
  [MIPS] Jazz: Retire use of plat_timer_setup.
  [MIPS] IP27: Convert to clock_event_device.
  [MIPS] JMR3927: Convert to clock_event_device.
  [MIPS] Always do the ARC64_TWIDDLE_PC thing.
