A couple of stylistic nits from Bruce.
If your libc contains version 1.11 or 1.12 of getcwd.c, (ie: if
you recompiled libc one of the last couple of days):
>>> Recompile LIBC before you boot a new kernel <<<
A new libc will deal with both old and new kernels.

We aren't sure if this new code and the old sound code will co-exist in a
kernel, so the device pcm0 line is left commented out in LINT.

While i was at it, also fixed a broken return value for the VT_RELDISP
ioctl, iff the third arg was legally VT_TRUE, but the destination
screen was in process mode so the actual switch had to be deferred.
This was breaking the ability to directly toggle between two X servers
running on two VTs, since the server getting the bogus error return
was running wild, and competing with the other one for the hardware.
(Sigh, this was a very long-standing bug.)

detail is passed back and forwards). This mostly came from NetBSD, except
that our interfaces have changed a lot and this funciton is in a different
part of the kernel.

The implementation is done (unlike what i've originally been
contemplating) by reparenting kids of processes that have the
appropriate bit set to PID 1, and let PID 1 handle the zombie. This
is far less problematical than what would seem to be ``doing it
right'', for a number of reasons.
Of our currently shipping PID-1-intended programs, 50 % fail the above
assumption. ;-) (Read this: sysinstall doesn't do it right. This is
no problem as long as no program called by sysinstall actually uses
SA_NOCLDWAIT.)
ToDo: . clarify the correct SA_* flag inheritance, compared
to other systems,
. decide whether the compat cruft (osigvec(9)) should
deal with new system additions or not,
. merge OpenBSD's SA_SIGINFO implementation. ;)

to write to a page, as a means of overriding `r-x COW' entries, but
causes failures in the `rwx' case.

large (over 4KB) softc struct. The descriptor array is accessed by
busmaster dma and must be physically contiguous in memory. malloc() of
a block greater than a page is only virtually contiguous, and not
necessarily physically contigious.
contigmalloc() could do this, but that is a bit on the overkill side.
I'm not sure of the origins of the problem report and diagnosis, I learned
of the problem via mail forwarded from Jim Shankland <jas@flyingfox.com>.
Jim said that Matt Thomas's workaround was to reduce the number of
transmit descriptors from 128 to 32, but I was concerned that it might
cost performance. Anyway, this change is my fault, not Jim's. :-)

Implement a function is_adapter_memory() in order to determine what
should nto be dumped at all. Currently, only populated with the ``ISA
memory hole''. Adapter regions of other busses should be added.
you don't want this (and the documentation explains why), but if you
use ipfw as an as-needed casual filter as needed which normally runs as
'allow all' then having the kernel and /sbin/ipfw get out of sync is a
*MAJOR* pain in the behind.

This code has been submitted by Luigi Rizzo <luigi@labinfo.iet.unipi.it>,
based on work done by Sujal Patel.
This currnetly doesn't provide the ability to register the port address
of PnP cards assigned a PnP driver. As there aren't any PnP capible
drivers yet, this isn't much of a problem.
The code allows you, through USERCONFIG, configure what the cards port
bases, irqs, and dma's are like. Currently there isn't support to view
what cards are in the sytem.
It successfully configures my PnP Internal Modem and sio then sees the
card as a normal isa device.

declaration macros so that a semicolon can be added when the macros
are invoked without giving a (pedantic) syntax error. Invocations
need to be followed by a semicolon so that programs like indent and
gtags don't get confused.
Fixed the one invocation that wasn't followed by a trailing semicolon.
