Damn, I just found a use for this in lguest.

Any chance of handing "next" to the sched_out hook so we can optimize
the lguest <-> lguest switch?

FYI, lguest turns off PGE globally when you load the module, because
turning it off on each guest entry v. slow.  With these hooks I can be
far smarter...

Thanks!
Rusty.
