fa60c9131a Very early and very *very* lightly tested support for LIVENGOOD chipset 
(followon to WISEMAN). Presumably some flavors are also no multimode copper
as well.

0630faf57d When wierdreset flag is set, turn on the DISADVFD flag when we reset 
rather than all the flags.  This prevents setting being read from ROM,
which is a problem.  If this breaks anything, it will only break the
3C556B cards minipci cards, which mainly exist at rpi as far as rpi
has been able to tell.

3ef73aae7e Fix problems booting large kernels on alphas. The symptom is that the kernel 
loads, prints the copyright, and either hangs or locks solid.  The
PC tends to be in the data segment and the RA is in XentMM

Doug really came up with the fix, I'm just the monkey typing.  Doug says:
	The alpha can only support 64k of globals with $gp pointing at
	base+32k so that the code can use 16bit signed offsets from $gp to
	access it. ....  it is possible to have multiple .got subsections
	and the linker handles this with the relocations for 'ldgp' pseudo
	instructions.  [Without this patch] the code in exception.s has been
	linked  to use a different gp from locore.s (where pal_kgp is set).

b2fadc6d14 The previous commit broke kernel builds on alpha (and probably ia64). 
#ifdef away the offending code until somebody with more newbus fu than
me can figure out where to put a default function that returns 255
without touching each alpha chipset driver..

eff8f28a1d * Correct some of my misunderstandings about how best to switch to the 
kernel backing store.
* Implement syscalls via break instructions.
* Fix backing store copying in cpu_fork() so that the child gets the right
  register values.

This thing is actually starting to work now. This set of changes takes me
up to the second execve (the one which runs the first shell). Next stop
single-user mode :-).

cd3bbf9dd5 Lots of little fixes. We no longer panic on card insert: 
o initialize ivars with bzero.
o remove interrupt function pointer.  netbsd needs it, but we don't.
o add lots of comments about bogus things that I've been kludging to try
  to make the simple cases work.
o add new ivar accessor for cis4 to match cis3.  likely neither will be
  needed, but it doesn't hurt to have it.

1f6d21dd38 Add nmbcnt sysctl and make it tunable at boottime; nmbcnt is the 
number of ext_buf counters that are possibly allocatable.

Do this because:

  (i) It will make it easier to influence EXT_COUNTERS for if_sk,
      if_ti (or similar) users where the driver allocates its own
      ext_bufs and where it is important for the mbuf system to take
      it into account when reserving necessary space for counters.

  (ii) Facilitate some percentile calculation for netstat(1)
