012c55b70a Set clock prescale based on BIOS supplied value instead of trying to
calculate an optimum value from (constant) parameters.
This should set the SCNTL3 register of the 53c860 and 53c875 to twice
the divider it used to be, since cards based on those chips seem to use
an 80MHz clock instead of the Clock Doubler feature and a 40MHz clock.

ccfe8b12a9 The socketpair(0 syscall is bogusly returning the fd numbers through
the primary and secondary return codes, causing it to not behave as
documented.  This probably originates from the ancient BSD kernels that
had pipe(2) implemented by socketpair(2), there are no binaries left that
we can run that do this.

ee3725a1c1 route.c:RTM_ADD does not check for a netmask before doing a tree walk
like it does elsewhere.  This is probably only happens when incorrect
args are given to route(8), or when running with non-IPv4 stacks but
incorrect args to the route command is no excuse for panicing!

e5048c6cd5 Some cleanups to the callout lists recently added.
note that at_shutdown has a new parameter to indicate When
during a shutdown the callout should be made. also
add a RB_POWEROFF flag to reboot "howto" parameter..
tells the reboot code in our at_shutdown module to turn off the UPS
and kill the power. bound to be useful eventually on laptops

966cbc5d29 Even though this looks like it, this is not a complex code change.
The interface into the "VMIO" system has changed to be more consistant
and robust.  Essentially, it is now no longer necessary to call vn_open
to get merged VM/Buffer cache operation, and exceptional conditions
such as merged operation of VBLK devices is simpler and more correct.

This code corrects a potentially large set of problems including the
problems with ktrace output and loaded systems, file create/deletes,
etc.

Most of the changes to NFS are cosmetic and name changes, eliminating
a layer of subroutine calls.  The direct calls to vput/vrele have
been re-instituted for better cross platform compatibility.

52457c88af for kern_conf.c, start allocating dynamic major numbers
half way through the range rather than possibly colliding with
fixed elements. Increase the size of the arrays to take this into account..
remember that each element in the array is now only 1 ponter  so this
isn't that much..

also note a possible bug in debugging code in uipc_socket2.c (add XXX)

11de36ed37 add callout lists for exit() and fork()
I've been meaning to do this for AGES as I keep having to patch those routines
whenever I write a proprietary package or similar..

any module that assigns resources to processes needs to know when
these events occur. there are existsing modules that should be modified
to take advantage of these.. e.g. SYSV IPC primatives
presently have #ifdef entries in exit()


this also helps with making LKMs out of such things..

(see the man pages at_exit(9) and at_fork(9))

b2b64697e4 move all functions related to shutting down to one file
called kern_shutdown.c

note: I couldn't see anything machine dependant in the
functions boot() and dumpsys() which were in machdep.c
I have left a prototype for cpu_boot() which would go in
machdep.c, but I have nothing to put in it. Iexpect others will
let me know in no uncertain ways that this or that  is machine dependant
and should be there, but I'll way for that to happen.. :)

I haven't actually taken the functions OUT of machdep
or anywhere else yet.. I'm checking in this file so others can have a look
at it and comment. SO PLEASE DO COMMENT!

I am also (in another checkin) addinf a man(9) page for the new
at_shotdown().. er freudian slip there.. at_shutdown() call
so have a look at that (and at_exit and at_fork as well)
and feed me comments..

I'll heck in the changes to make these (shutdown) changes active tomorrow
if no-one objects too strongly..

5de44aa3b7 Add __unused to the list of __dead, __dead2, __pure, __pure2 etc.
gcc-2.7 has __attribute__((unused)) as a postfix operator on function
arguments to prevent -Wunused from complaining about them.  gcc < 2.7
doesn't have anything like this (and doesn't care about it either).

eg:
int foo(bar, baz)
  int bar __unused;	/* needed because of function pointer typing */
  char *baz __unused;
{
  return (1);

dcde70f16b Fix two minor oddities introduced by my yesterday's patches:
. preserve a multi-char sequence in a small static buffer inside
  pccngetc(), so it won't be clobbered later (used to happen when
  breaking into DDB user Ctrl-Alt-ESC), and

. simplify the ``keystroke is present'' determination in sgetc(), thus
  making pccncheck() actually working without waiting for a keystroke.
