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.

Abandon disabled_mask and spl_mask, and use only current_spl_level to
...
manage interrupt masking.
This change is necessary for straightforward implementation of coming IPL
support for cascaded intrs, and it should not impair performance.

Add `l_poll' to `struct linesw' and provide an xxxpoll() entry point

Sprinkle pmap_update() calls after calls to:
...
- pmap_enter()
- pmap_remove()
- pmap_protect()
- pmap_kenter_pa()
- pmap_kremove()
as described in pmap(9).
These calls are relatively conservative. It may be possible to
optimize these a little more.
