s390/idle: allow arch_cpu_idle() to be kprobed (8d93b701) · Commits · 戴 / test

Remove NOKPROBE_SYMBOL() for arch_cpu_idle(). This might have made sense when enabled_wait() (aka arch_cpu_idle()) was called from udelay. But now there shouldn't be a reason why s390 should be the only architecture which doesn't allow arch_cpu_idle() to be probed. Signed-off-by:
