 How is this a duplicate of kern/20523?  That PR deals with multi-port PCI
 serial devices, where this just deals with single-port PCI serial devices --
 unless it's just a generalization.
 
 The originator of kern/40636 has not seen any performance problems with my
 patch, so unless sharing intr_fast (whatever the heck that is -- I can't
 find any mention of that in the sio.c file) is some very bad thing to do, I
 don't see a problem with my patch.
 
 Can someone please clarify?
