Merge branch 'clocksource/cleanup' into next/cleanup

Clockevent cleanup series from Shawn Guo.

Resolved move/change conflict in mach-pxa/time.c due to the sys_timer
cleanup.

* clocksource/cleanup:
  clocksource: use clockevents_config_and_register() where possible
  ARM: use clockevents_config_and_register() where possible
  clockevents: export clockevents_config_and_register for module use
  + sync to Linux 3.8-rc3
