bf709d2564 3 changes:
1/ Makefile:  the maximum size for boot2 is 7.5K not 7K,
so don't complain until it reaches THAT size..
newfs leaves 8K and boot 1 is 512k. leaving 7.5K becasue the disklabel
is considered to part of the boot2 file.

[512  boot1][512 disklabel][     7K boot2 code        ]
[boot1 file][               boot2 file                ]

2/ Boot2.S: move the soring of the default name read from block 2 to AFTER
clearing the BSS.

3/ boot.c:
Move the parsing of the command line into the
place it's called for clarity.. alsoi comment it a bit and clean it
up a bit.. for some reason this seems ot have made it a little
larger, but I can't work out why.. maybe bruce might have ideas?
compensated for by shrinkage elsewhere..

the practical result of this is htat the default string can now contain args
e.g. if you change the default string to have -gd
then the machine will boot to the dgb debugger stub by default..
this is mostly useful with the nextboot utility..
as it now allows you to remotely force a machine to reboot into
the debugger.

6bce784d06 Changed type of ni_dirp in struct namei' from caddr_t to const char *'
so that the compiler can see that it is OK to use const strings in

e7fa2650cc `struct linker_set execsw_set' was declared as const and pointers in it

7fa8a688aa Add preliminary support for the Orion PCI chip set. It is special in the
way it attaches multiple PCI buses directly to the CPU, instead of having
them hanging off from PCI to PCI bridges. This code is a hack, and will
be obsoleted by the planned rework of the PCI code, which will change the
dealing with PCI to PCI bridges and other special devices significantly.

The patch also adds a kern_devconf entry for PCI bus 0 which is assumed
to be a child of cpu0. The new PCI code will make it possible to hand out
the kern_devconf structure to a pci device being attached, since this is
(regretably, IMHO) required by a few ISA devices.

Finally there are new PCI ids for some Intel chip set devices, which had
already been known to 2.1.5R, but did not make it into -current. This closes
"kern/1558: PCI probe seems to have lost a device in -current".

e3bc07db0d If the basemem value supplied by the bootblocks, differs from the value
returned by the RTC, use the bootblock supplied value.  Also, map the
'stolen by BIOS' memory in the same manner as the ISA-hole memory, since
it is really an extenstion of the BIOS.  This is necessary for 32-bit
BIOS functions such as APM support on laptops, and the loss of memory
for non-necessary functions seems to be at most 4k.

62494ee3f3 Sorted and fixed tabs.
The only excuse this had for becoming misordered was that some drivers
were sorted on the driver name field, but the ffs versus mfs ordering
shows that this is not a consistent order.

The only case that I know of where simple sorting is wrong is for files
that must be compiled without profiling if profiling is configured and
normally otherwise.  Then the line with `profiling-routine' must appear
first to get the file compiled with ${PROFILE_C}.

6476c0d204 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.

979ef59bf8 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);

89e85b2828 Apply my small patch to make detection of ATAPI CD-ROMs happen a
little more reliably. So far I've received a couple of positive
responses and no objections to these changes.

There are two one-line changes:

- In wdprobe(), when testing the error status of drives, don't
  unconditionally decide that there is no controller present if we
  read back a value of 0x81 (drive 0 okay, drive 1 failed) twice
  in a row. This may be caused by having an ATAPI CD-ROM jumpered
  as a master on the controller with no slave.

- In wdgetctlr(), when checking for a status of WDCS_READY, check the
  value twice. The first time may be bogus. This stops a phantom wd2
  device from being detected when an ATAPI CD-ROM is attached to the
  secondary controller alone as a slave. (This can cause installation to
  fail when sysinstall attempts to open the phantom device and wedges the
  system as a result. This has bitten me a couple of times on some
  Gateway 2000 machines.)

fae988778b Fix many long-standing bugs and problems with pcvt, namely:
. make pccncheck() work even when interrupts are disabled, so the
  ``Press a key on the console...'' procedure will work,
. make kernel colors #ifndef, so they can be overridden from the
  config file,
. use shutdown_nice() instead of cpu_reset() if Ctrl-Alt-Del is
  enabled,
. allow pccngetc() to return more than a single character, so the
  arrow keys will work (and thus visual UserConfig!),
. fix a warning.

This closes all know PRs related to pcvt, in particular #845, #1236,
and #1265.  PR #991 is a duplicate for 845, and PR #1283 has already
been fixed earlier in rev 1.11 of pcvt_conf.h.

This is a patch to sys/net/if.c. What it does is patch the algorithm
for finding an IP address on an interface which most closely matches
a given IP address. The problem with it is when no address matches,
and you have to just pick one at random. Then the code ends up picking
the last IP address in the list. This patch changes things so it
picks up the first address instead.
Usually the first address is more useful as the later ones are aliases.

	   I added lookup hints to minimize the need for the
	   page table lookup operations.
	3) Removal of some bogus performance improvements, that
	   mostly made the code more complex (tracking individual
	   page table page updates unnecessarily).  Those improvements
	   actually hurt 386 processors perf (not that people who
	   worry about perf use 386 processors anymore :-)).
	4) Changed pv queue manipulations/structures to be TAILQ's.
	5) The pv queue code has had some performance problems since
	   day one.  Some significant scalability issues are resolved
	   by threading the pv entries from the pmap AND the physical
	   address instead of just the physical address.  This makes
	   certain pmap operations run much faster.  This does
	   not affect most micro-benchmarks, but should help loaded system
	   performance *significantly*.  DG helped and came up with most
	   of the solution for this one.
	6) Most if not all pmap bit operations follow the pattern:
		pmap_test_bit();
		pmap_clear_bit();
	   That made for twice the necessary pv list traversal.   The
	   pmap interface now supports only pmap_tc_bit type operations:
	   pmap_[test/clear]_modified, pmap_[test/clear]_referenced.
	   Additionally, the modified routine now takes a vm_page_t arg
	   instead of a phys address.  This eliminates a PHYS_TO_VM_PAGE
	   operation.
	7) Several rewrites of routines that contain redundant code to
	   use common routines, so that there is a greater likelihood of
	   keeping the cache footprint smaller.

c268c94f6b FINALLY: PCI support for the Lance Ethernet driver.
This code applies to several systems with integrated Ethernet
chip, for example from HP or Compaq. It should also support
PCI Ethernet cards based on the AMD PCI Lance chip.

This code has been reviewed (visually) by Paul Richards and
tested (using an ISA Lance board) by Joerg Wunsch.
Since the parameters to nearly each and every single function
had to be changed (generally from unit number to lnc_soft*),
there is some potential for buglets having crept in ...

BEWARE: If you had lnc0 configured to have the ISA probe find
your PCI Lance, then it should now be found by the PCI probe,
and should be automatically configured as pci1 (!!! note the "1").

09c6884729 Various fixes from frank@fwi.uva.nl (Frank van der Linden) via
rick@snowhite.cis.uoguelph.ca:

1. Clear B_NEEDCOMMIT in nfs_write to make sure that dirty data is
correctly send to the server.  If a buffer was dirtied when it was in
the B_DELWRI+B_NEEDCOMMIT state, the state of the buffer was left
unchanged and when the buffer was later cleaned, just a commit rpc was
made to the server to complete the previous write.  Clearing
B_NEEDCOMMIT ensures that another write is made to the server.

2. If a server returned a server (for whatever reason) returned an
answer to a write RPC that implied that fewer bytes than requested
were written, bad things would happen.

3. The setattr operation passed on the atime in stead of the mtime to
the server. The fix is trivial.

4. XIDs always started at 0, but this caused some servers (older DEC
OSF/1 3.0 so I've been told) who had very long-lasting XID caches to
get confused if, after a reboot of a BSD client, RPCs came in with a
XID that had in the past been used before from that client. Patch is
to use the current time in seconds as a starting point for XIDs. The
patch below is not perfect, because it requires the root fs to be
mounted first. This is because of the check BSD systems do, comparing
FS time to system time.

4611b39710 Enable transmit complete interrupt...
(author's explaination):

 Bit 15 is the flag to request a transmit complete interrupt.  The
driver was apparently written to minimize interrupts, and if not for a
3-COM design quirk, everything would be just ducky.
 Prior to loading the outbound packet into the FIFO, the driver checks
to see if there's enough space to contain the packet.  If not, the
driver requests a transmit-available interrupt when there is
sufficient room.  Unfortunately, the card is continuing to process the
prior FIFO, and by the time the driver sets the threshold for a
transmit available interrupt, the space is already available.  When
this occurs, the 3COM card ignores the interrupt request, and the
driver is hung waiting for an interrupt that will never occur.
There's probably a more elegant solution, but requesting the transmit
complete interrupt was the easiest to implement.  An alternative fix
might be to check free FIFO space again, after requesting the transmit
available interrupt, but I haven't bothered pursuing this.  Since the
patch, my 3C590 (PCI, same FIFO interface as 3C509) has been rock
solid.

timer processing on a TCB to always stop after a single timer had
expired (because it misinterpreted the return value from tcp_usrreq()
to indicate that the TCB had been deleted).  Finally, some code

1e4ad9ce28 This is a proposal-in-code for a substantial modification of the way
the high kernel calls into a protocol stack to perform requests on the
user's behalf.  We replace the pr_usrreq() entry in struct protosw with a
pointer to a structure containing pointers to functions which implement
the various reuqests; each function is declared with the correct type and
number of arguments.  (This is unlike the current scheme in which a quarter
of the requests take arguments of type other than (struct mbuf *) and the
difference is papered over with casts.)  There are a few benefits to this
new scheme:

1) Arguments are passed with their correct types, and null-pointer dummies
   are no longer necessary.

2) There should be slightly better caching effects from eliminating
   the prximity to extraneous code and th switch in pr_usrreq().

3) It becomes much easier to change the types of the arguments to something
   other than `struct mbuf *' (e.g.,pushing the work of sosend() into
   the protocol as advocated by Van Jacobson).

There is one principal drawback: existing protocol stacks need to
be modified.  This is alleviated by compatibility code in
uipc_socket2.c and uipc_domain.c which emulates the new interface
in terms of the old and vice versa.

This idea is not original to me.  I  read about what Jacobson did
in one of his papers and have tried to implement  the first steps
towards something like that here.  Much work remains to be done.

on block 1 of the disk (2nd block), should the correct magic numbers be present.

If the correct options are used it will 'delete' the name used from block1,
thereby assuring that if the boot fails it won't be stuck in an infinite loop.

the boot strings are set by the utility "nextboot"
(not yet checked in, but being tested.)
By default these changes should have no effect on existing installations
and if compiled without the NAMEBLOCK option should be essentially identical
to the old ones.

d805b866fa This driver supports the SDL Communications RISCom/N2 ISA cards that is
based on the HD64570 chip. Both the 1 and 2 port cards is supported.

Line speeds of up to 2Mbps is possible. At this speed about 95% of the
bandwidth is usable with 486DX processors.

The standard FreeBSD sppp code is used for the link level layer. The
default protocol used is PPP. The Cisco HDLC protocol can be used by
adding "link2" to the ifconfig line in /etc/sysconfig or where ever
ifconfig is run.

At the moment only the X.21 interface is tested. The others may need
tweaks to the clock selection code.
