If it's in perf_event_print_debug() there isn't much to check. sparc_pmu is derefernced in the loops, but the first thing this function does is check it against NULL and return immediately if it is NULL. pcr_ops is dereferenced also, but pcr_ops should never be NULL if sparc_pmu is not NULL. Hmmm... that's setup by pcr_arch_init() which I only see being invoked by smp_cpus_done(). Is this a uniprocessor build? -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
