the weird "pass by reference" that causes problems with gcc4.

with a VIA 686 southbridge.
Features:
- 686 setup code (no thanks to PMON for not initializing the beast).
- work in progress ISA interrupt handling code.
- support for vga(4) compatible devices as console, in PC-compatible text mode.
- move legacy (ISA) support code out of bonito(4) to make things clearer.
- support more than 256MB on 2E-based systems.
Tested on a generic 2E-based evaluation board by someone who wishes to remain
anonymous; you know who you are, thank you very much for testing.

numbers are a PITA in the long run; from NetBSD.

If userland asks to allocate an object large enough that two that size
could not fit around the pinned objects, disallow it with EFBIG.
This prevents mmap of large objects that big and copying between them
putting the machine into infinite thrashing. with a patch to the ddx (on
my git branch) that allocates a non-accelerated pixmap when it gets that
return code, matthieu@s test huge image works happily when before it
DOSed the kernel.
The correct fix would be to fall back to mmaping the backing pages for
objects that big (radeondrm will need such ability anyway). This however
is a lot more complicated and I am still working out how to do it
correctly hence this commit for now.

We need a proper MI api for doing this (one which will fall back to
mtrrs if PAT is not available would be best), but for now this allows
inteldrm to use PAT if available. Big fat XXX mentioning the need for a
real api.

PAT allows setting per-mapping cachability bits. Our main interest in it
for write combining mappings so we do not have to rely so heaviliy on
mtrrs (which are stupidly set up on more and more machines). MD flags to
pmap allow setting these bits (which bus_space now uses for PREFETCHABLE
maps), if a vm page has a bit set, then we will use WC for all mappings
of a page (used for userland mappings). We also check for known errata
and fall back to UC- mappings in that case.

to the new MAC. But subsequently added ports were still being assigned the
old MAC address because it was copied from the wrong place. Give newly added
trunk ports the current MAC of the master port, rather than the saved MAC of
the master port. The saved MAC should only be used to restore the original
MAC address of the interface when it is removed from the trunk.

call the interface-specific ioctl handler as well in case the driver
needs to do something special. E.g. if_trunk expects this in order to
update MAC addresses of its trunk ports.
If you now see "Inappropriate ioctl for device" errors after running
"ifconfig $if lladdr random" please let me know. Most likely the ioctl
handler of the driver needs fixing.

over other addresses configured on the same interface.
Facilitates peaceful coexistence of temporary addresses for outgoing
connections and static addresses for incoming connections.

accept flags for report and nocloning. Move the rtableid into struct route
(with a minor twist for now) and make a few more codepathes rdomain aware.
Appart from the pf.c and route.c bits the diff is mostly mechanical.

by reference for the trap frame, the infrastructure in locore.S for this
was already present.
This prevents gcc4 from optimising away stores into the frame and allows
a gcc4-compiled kernel to boot.

tsleep'ing (for example waiting for the firmware to become alive)
in iwn_init.
I believe this might fix a crash reported by dhill@
This is a temporary fix until I find something better that I will
apply to my other drivers that can tsleep in if_init (wpi, run etc...)

the non-line-discipline-specific ioctl handler should be tried.
So changing these to return ENOTTY was wrong.

into a magic register. Simplify the code by making this explicit, but keep
the dummy read just in case this has a magic side-effect. And yes, as far as
I can tell, writing 0 is really what was intended here. Makes gcc4 happy.
No binary change with gcc3.

On AViiON systems with the 6:1 CMMU:CPU configuration, force cached
mappings to be writethrough - this probably hides a bug in the code, but
that's the only way so far to get such a system running stably.

I forgot that uvm_object.c wasn't build if SMALL_KERNEL. Fix this by building
the file unconditionally and only building the less used functions when
SMALL_KERNEL is not defined.

places in the tree need to be touched to update the object
initialisation with respect to that.
So, make a function (uvm_initobj) that takes the refcount, object and
pager ops and does this initialisation for us. This should save on
maintainance in the future.
looked good to fgs@. Tedu complained about the British spelling but OKed
it anyway.

If when we have successfully swapped an aobj back in, then we release our
reference count, and that reference is the last reference, we will free the
the aobj and recursively lock the list lock.
Fix this by keeping track of the last object we had a reference on, and
releasing the refcount the next time we unlock the list lock.
Put a couple of comments in explaining lock ordering in this file.
