Looks good.  The kern_intr.c diff has a small bug (forgot to remove the return 
(intr_event_create(...)) from swi_add()).  A few style suggestions would be 
to always leave a blank line before a comment (I think I saw this in 
kern_calloutwheel_init()?) and usually there isn't a blank line before a 
SYSINIT().  Maybe make the panic messages when creating softclock threads 
more specific, but that's very minor.
