5d5e7cf75e bootpath detection: some (newer?) v2 prom versions use actual device address, 
e.g. `/fd@1,72000000'.

e2655dd7cc Allow DIAGNOSTIC kernels a FLUSHWIN trap in order to record stack traces

fbc5fd1fca Bound the buffer cache to 1/2 of kernel virtual memory, so machines with 
lots of core don't run out of core (takes care of PR#2506).

f87e51fb6b Turn on RB_ASKNAME if a `swap generic' kernel was not able to determine

4dd7cb4f5c Use ic_*' cacheinfo fields, and in the split-I&D case, derive c_linesize[l2]' 
from from the corresponding `ic_*' and `dc_*' values. This is not perfect,
but it makes SS4s and SS5s run until we have proper per-cpu cache handling.

Use the `cache-physical?' property to determine the value of `vactype'
on sun4m's. If absent, set vactype to VAC_WRITETHROUGH (XXX) else VAC_NONE.

Print simpler sun4m CPU identifier on attach.

57e61589e7 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.

(hopefully I'll get a few of my hairs back now..)
