Paul Gortmaker 28956e530b tick/nohz: Use WARN_ON_ONCE() to prevent console saturation ... commit 40e97e42961f8c6cc7bd5fe67cc18417e02d78f1 upstream. While running some testing on code that happened to allow the variable tick_nohz_full_running to get set but with no "possible" NOHZ cores to back up that setting, this warning triggered: if (unlikely(tick_do_timer_cpu == TICK_DO_TIMER_NONE)) WARN_ON(tick_nohz_full_running); The console was overwhemled with an endless stream of one WARN per tick per core and there was no way to even see what was going on w/o using a serial console to capture it and then trace it back to this. Change it to WARN_ON_ONCE().
