In ppc64 config if `CONFIG_SOFTLOCKUP_DETECTOR` is not set then it warns for unused declaration of `watchdog_allowed_mask` while building, move the declaration inside ifdef later in the code.
kernel/watchdog.c:47:23: warning: ‘watchdog_allowed_mask’ defined but not used [-Wunused-variable]
static struct cpumask watchdog_allowed_mask __read_mostly;
