Take advantage of new am7990 sc_nocarrier() function in order to do auto-
...
matic media detection on Sun4m machines which support multiple media
(UTP and AUI). New function lenocarrier() switches media type when called
if no link? flags are set.
Redefine link flags for Lance ethernet (le):
<none>: switch between media as needed to find carrier (autodetect)
Preference to whatever the PROM is using (AUI if not booted
from the network)
link0: use UTP port only
link1: use AUI port only
This allows Sun4m machines with dual media Lance ethernet adapters to
boot from the network on the UTP port.

Fix two cases of handling stale page table information:
...
1. when reading the referenced/modified bits the TLB entry must be flushed
before reading the in-core version.
2. when wrapping up an entire segment in pmap_page_protect(), flush the PTPs
from the TLB to prevent a table-walking operation to pick up stale - or
possibly bogus - PTEs.
