hm, such x86 infrastructure changes should be submitted via the x86 
tree, and you should at least have Cc:-ed the maintainers.

The thing is, we are _getting rid_ of the idle notifiers, not extending 
them. The last thing we need is random opaque stuff getting called in 
weird ordering when we enter/exit idle state. We want all that be 
visible and have explicit, in-source-code ordering.
