The original use cases were: - Accounting for idle time with stopped counters in oprofile and eliminate the need for idle=poll. That never was implemented unfortunately but would be still a worthy feature I think. - Perfmon for similar uses. - noidletick -- my original noidletick implementation used the idle notifiers similar to the s390 implementation. Obsolete now. Right now it is used for the machine check early notification, but I never liked that (imho it just "fixes" a non problem only relevant in non realistic testing situations) and it would be fine to drop that one I think. In fact I already made it a config in the patchkit to use the 64bit mce code on 32bit too. -Andi
