stop_machine: Make stop_cpus() static
The function stop_cpus() is only used internally by the stop_machine for stop multiple cpus. Make it static. Signed-off-by: Yangtao Li <tiny.windzz@gmail.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Link: https://lkml.kernel.org/r/20191228161912.24082-1-tiny.windzz@gmail.com
