43a67e5367 Add preliminary support for the 53c860 and 53c875 ULTRA SCSI chips,
and for the 53c810ap, the improved version of the 53c810.
The driver should work with all those controllers, but doesn't know
about any of their advanced features.

e18c331b1e Add support in TCP for Path MTU discovery. This is highly experimental
and gated on `options MTUDISC' in the source.  It is also practically
untested becausse (sniff!) I don't have easy access to a network with
an MTU of less than an Ethernet.  If you have a small MTU network,
please try it and tell me if it works!

3acddf4543 Now supports expand all' and collapse all'.
Now comes up in the old line-oriented interface by default for serial
and pcvt folk with a `visual' command for going to the visual interface.
Best of both worlds, no?

ad23d1b01e Generate prototypes for syscall-implementing functions. Put them in
<sys/sysproto.h> and use them (so far only) in kern/init_sysent.c.

Don't put $Id in generated files.

kern/syscalls.master:
I had to add some new fields to describe some non-orthogonal names.
E.g., the args struct for the syscall-implementing function foo()
is usually named `foo_args', but for getpid() it is named `args'.

sys/sysent.h:
sy_call_t is still incomplete to hide a couple of warnings.

Changes relative to 1.12:

1388e34c46 Check the return value from vm_map_pageable() when mapping the process's

behavior of panicing with a "kernel page directory invalid" in pmap_enter.

cbe2819c8f Our existing Cyrix cache-disable code was short-cutting the steps for
setting the control register.  Make the read and write operations two
completely separate steps.

While we're at it, pull in the whole set of Cyrix cache control options
from NetBSD-current,  since a few motherboards do the right thing with
the Cyrix chip.

There is no option to disable the internal cache completely (yet).

9237addf83 Check for page being resident when doing I/O with /dev/kmem and return
EFAULT if it is not resident. This prevents the system from manufacturing

5dd40fdb4a Another try to determine the PCI bus configuration mode (and whether
there is a PCI bus at all) ...

- Do not expect the chip sets to follow even very clearly expressed
  requirements of the PCI 2.0 spec.
- Do not read back the value just written to an I/O port without making
  sure that some other data have crossed the bus in between ...

b25bd8fa0d 1) Killed 'BSDVM_COMPAT'.
2) Killed i386pagesperpage as it is not used by anything.
3) Fixed benign miscalculations in pmap_bootstrap().
4) Moved allocation of ISA DMA memory to machdep.c.
5) Removed bogus vm_map_find()'s in pmap_init() - the entire range was
   already allocated kmem_init().
6) Added some comments.

virual_avail is still miscalculated NKPT*NBPG too large, but in order to
fix this properly requires moving the variable initialization into locore.s.

2c2abd6c04 From Bruce Evans: (prototype related changes, other cleanups)
Add prototypes.  Use static for function definitions to match existing
prototypes.  Otherwise leave functions that should be static as extern.
TODO: declare everthing except sidriver and siintr as static.  I use
some new cdevs registration functions to do this for syscons and pcvt.

Fix siintr() to match its prototype in ioconf.c (don't return anything).
This may break the eisa support, but Julian says that eisa interrupts
never worked anyway.

(EISA support was never tested anyway - Peter)

7a80a4be51 Increased SOMAXCONN from 5 to 32. 5 was too small a value for just about
any reasonably busy machine, and by any measure is a lousy "max" value.
32 was chosen after a careful analysis of typical listen queue depths
on several busy Internet servers (both web and ftp). I also intend to
add a statistics counter for dropped connection requests due to the limit
being exceeded.
