My view is this is going to be tricky because:
- we use tasklets. When we  reschedule we can end up on a differrent
cpu. 
-I dont see any point in having a separate softIRQ 
- and if you do use other mechanisms it would require a lot more
testing since there are quiet a few use cases of ifb

cheers,
