ARM: localtimer: clean up local timer on hot unplug
When a CPU is hot unplugged, the generic tick code cleans up the clock event device, but fails to call down to the device's set_mode function to actually shut the device down. To work around this, we've historically had a local_timer_stop() callback out of the hotplug code. However, this adds needless complexity when we have the clock event device itself available. Explicitly call the clock event device's set_mode function with CLOCK_EVT_MODE_UNUSED, so that the hardware can be cleanly shutdown without any special external callbacks. When/if the generic code is fixed, percpu_timer_stop() can be killed off. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
