Ok, not only does that fix the bug, but it simplifies the code and looks 
obviously ok. However, I don't have it in my tree yet, and I'd like to do 
an -rc3 that has this fixes (so that along with the PCI MSI thing, we 
hopefully have most of the suspend/resume regressions fixed).

And I was hoping to do -rc3 today. Can I please have pull-requests for the 
appropriate urgent scheduler/x86 fixes? Or should I just take these as 
patches?
