fcdc02160f Add option ICMP_BANDLIM_SUPPRESS_OUTPUT to the mix. With this option,
badport_bandlim() will not muck up your console with printf() messages.

24488c7498 Provide a temporary undocumented option: SHM_PHYS_BACKED. This will
become sysctl and/or flags controlled later.  It's mainly here for an
easy place to test the physical memory backed objects.

0385347c1a Implement an optimization of the VM<->pmap API. Pass vm_page_t's directly
to various pmap_*() functions instead of looking up the physical address
and passing that.  In many cases, the first thing the pmap code was doing
was going to a lot of trouble to get back the original vm_page_t, or
it's shadow pv_table entry.

Inspired by: John Dyson's 1998 patches.

Also:
Eliminate pv_table as a seperate thing and build it into a machine
dependent part of vm_page_t.  This eliminates having a seperate set of
structions that shadow each other in a 1:1 fashion that we often went to
a lot of trouble to translate from one to the other. (see above)
This happens to save 4 bytes of physical memory for each page in the
system.  (8 bytes on the Alpha).

Eliminate the use of the phys_avail[] array to determine if a page is
managed (ie: it has pv_entries etc).  Store this information in a flag.
Things like device_pager set it because they create vm_page_t's on the
fly that do not have pv_entries.  This makes it easier to "unmanage" a
page of physical memory (this will be taken advantage of in subsequent
commits).

Add a function to add a new page to the freelist.  This could be used
for reclaiming the previously wasted pages left over from preloaded
loader(8) files.

642ba07a24 If we are running in APIC_IO mode, pretend that we didn't see the BIOS
reporting an AT PIC.  We do this because otherwise the PIC will claim
IRQ 2 in an unshareable mode, preventing other devices from legitimately
using it.

For symmetry, in !APIC_IO mode, ignore the APIC if it's reported.

This is a hack; a better solution would have the PIC's driver release
the IRQ if it was not going to be active.

2e2de7f23f Move code to handle BPF and bridging for incoming Ethernet packets out
of the individual drivers and into the common routine ether_input().
Also, remove the (incomplete) hack for matching ethernet headers
in the ip_fw code.

The good news: net result of 1016 lines removed, and this should make
bridging now work with *all* Ethernet drivers.

The bad news: it's nearly impossible to test every driver, especially
for bridging, and I was unable to get much testing help on the mailing
lists.

558d6032c2 Turn on USB support for most USB devices. udbp is not turned on since
NETGRAPH is not present in GENERIC at the moment.  Also, change some
settings to support USB installs:

- Add KBD_INSTALL_CDEV as an option to make /dev/kbd[01] actually work.
- Turn on keyboard probing in sc0.  The syscons driver will now use a
  flag documented in ukbd(4) but not in sc(4) that tells syscons to
  actively search for a keyboard device if none is found.  This allows
  USB keyboards to just be plugged in and instantly start working.
- Require the atkbd0 driver to actually probe to see if a keyboard is
  there.  This allows USB keyboards to be seen by sc0 if an AT keyboard
  isn't plugged into the computer.  This also means that you will no
  longer be able to plug an AT keyboard into a machine after it has
  booted a GENERIC kernel and use it.  AT keyboards aren't designed for
  this anyway.  USB keyboards are designed for this, and they work.

6acb7e5a81 Attempt to work around problems caused by spurious interrupts and
uninitialised interrupts in the APIC.  This seems to fix the problems
being seen on systems using the RCC chipsets, eg. Dell PowerEdge 24x0.

The actual nature of the problem probably needs further investigation,
but this patch allows us to actually function on these systems.

<sys/bio.h> is now a prerequisite for <sys/buf.h> but it shall

subject of nested includes.

Diskdrivers and similar stuff below specfs::strategy() should no

Still a few bogus uses of struct buf to track down.

b5ea1f0c77 The USB double bulk pipe driver (Host to host cables). Currently there
are two supported chips, the NetChip 1080 (only prototypes available)
and the EzLink cable. Any other cable should be supported however as they
are all very much alike (there is a difference between them wrt
performance).

It uses Netgraph.

This driver was mostly written by Doug Ambrisko and Julian Elischer and
I would like to thank Whistle for yet another contribution. And my
aplogies to them for me sitting on the driver for so long (2 months).

Also, many thanks to Reid Augustin from NetChip for providing me with a
prototype of their 1080 chip.

Be aware of the fact that this driver is very immature and has only been
tested very lightly. If someone feels like learning about Netgraph however
this is an excellent driver to start playing with.

ab063af911 Move the MSG* and SEM* options to opt_sysvipc.h
Remove evil allocation macros from machdep.c (why was that there???) and
use malloc() instead.
Move paramters out of param.h and into the code itself.
Move a bunch of internal definitions from public sys/*.h headers (without
#ifdef _KERNEL even) into the code itself.

I had hoped to make some of this more dynamic, but the cost of doing
wakeups on all sleeping processes on old arrays was too frightening.
The other possibility is to initialize on the first use, and allow
dynamic sysctl changes to parameters right until that point. That would
allow /etc/rc.sysctl to change SEM* and MSG* defaults as we presently
do with SHM*, but without the nightmare of changing a running system.
