Current CPU_SEQID users don't care about possibly changing CPU ID, but enclose it within kpreempt disable/enable in order to fend off warnings from Linux's CONFIG_DEBUG_PREEMPT. There is no need to do it. The expected way to get CPU ID while allowing for migration is to use raw_smp_processor_id. In order to make this future-proof this patch keeps CPU_SEQID as is and introduces CPU_SEQID_UNSTABLE instead, to make it clear that consumers explicitly want this behavior.
