have a disk. Device is commented out on all non-GENERIC kernels.

to access user memory (writing the register windows back to the stack)

All those kernels have a line for both tun and bridge, and if either is
commented out, tap is commented out also. With the exception of i386's

In order for topdown uvm to be an option on ports using PMAP_PREFER,
they will need to "prefer" lower addresses if topdown is being used.
Additionally, at least one port also needs to know the size.
allocate a stack frame for blast_dcache() when profiling so it shows up.
in dcache_flush_page(), use a stride of 32 instead of 16 to match the
cache line size. correct various comments.
(ie. just before we skip the per-page cache invalidations while tearing down
each context) instead of just before we recycle all the contexts in ctx_alloc().
the latter is not good enough since a (physically tagged) L1 cache line is
valid for all contexts, not just the one that was used to instantiate it.

is ... slightly confusing. Instead calculate the total size of the dump
beforehand and show the number of MB we still need to dump instead - just
like 386 does it.
It looks like bit 3 control the on-board le's link test, clearing it breaks
the interface (no link detected on the remote end). bit 3 is defined as
AUXIO4M_LTE (link-test enable) for sun4m systems (maybe all the AUXIO4M_*
bits are valid on the Ultra/1 too ?).
Tested on Ultra/1 and Ultra/5, approved by Martin Husemann and Matthew Green.

which bustype should be attached with a specific call to config_found()
(from a "mainbus" or a bus bridge).
Do it for isa/eisa/mca and pci/agp for now. These buses all attach to
an mi interface attribute "isabus", "eisabus" etc., and the autoconf
framework now allows to specify an interface attribute on config_found()
and config_search(), which limits the search of matching config data
to these which attach to that specific attribute.
So we basically have to call config_found_ia(..., "foobus", ...) where
such a bus is attached.
As a consequence, where a "mainbus" or alike also attaches other
devices (eg CPUs) which do not attach to a specific attribute yet,
we need at least pass an attribute name (different from "foobus") so
that the foo bus is not found at these places. This made some minor
changes necessary which are not obviously related to the mentioned buses.

XXX - this should be handled more consistent across the different

we have neither rtc nor file system time -- to this millenium.
