Subject[PATCH] [PATCH] time: tick-sched: use bool for tick_stopped
 From: John Zhao <yuankuiz@codeaurora.org>

Variable tick_stopped returned by tick_nohz_tick_stopped
can only be true / false values. Since the return type
of the tick_nohz_tick_stopped is also bool, variable
tick_stopped nice to have data type as bool in place of int.
Moreover, the executed instructions cost could be minimal
without potiential data type conversion.
