toshii 822c8273de Instead of scheduling all interrupts at IPL_BIO, use an IPL_SERIAL
handler to clear hardware interrupt bit and schedule actual handlers
using soft interrupts registered with desired IPL.

XXX This slows down interrupt handling a bit (up to a few percent with
XXX ping -f or make-over-NFS benchmarks) in some cases.
