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 Signed-off-by: Olof Johansson <olof@lixom.net> Conflicts: arch/arm/mach-pxa/time.c
