Steven ??? Yeah, I talked with Daniel too about it. I need to look more into it. I haven't had time since I'm spending the weekend (Monday too, since it's a holiday in the US), moving to my new house. There is a race, but honestly, it will be a merical to happen, and if it does, it only gives the results that we had "before" the patches ;-) But take them out, until I get to the bottom of them. But that won't be until "earliest" Tuesday.

I'm not sure which latency tracing fixes these are, but Steven's
get_monotonic_cycles() changes are racy .. It might be a little
premature to include them .. It at least fouls latency tracing on my
test machine.

The PICK_OP changes got reviewed by Ingo , as of,
http://marc.info/?l=linux-rt-users&m=118638506125380&w=2
They do need one small fix tho .. Below ..
