805b2d4d90 1) Set ipending back to 4, because (16 + 4) bit not in
netmask or impmask.

2) Fixes from Bruce:
	o Changed name of schedsoftcom() to setsofttty() to match
	  setsoftclock()
	o Bool_t isn't used.
	o tx_fifo_size is 1 for chips without fifos, 16 for 16550's, to
	  help to output more efficiently for 16550's (LSR_TXRDY means
	  that the fifo is empty, not that it has space for one char).
	o Changed name of softsio1() to siopoll() and merged compoll()
	  into siopoll().
	o The probe forgot to clear com_mcr after it failed.  This is
	  harmful for 4 single serial ports on 2 interrupts.  It makes
	  partial misconfigurations worse.
	o Don't bother initializing static variables that are 0 (bidir
	  stuff).
	o Only initialize t_oflag to TTYDEF_OFLAG if unit == COMCONSOLE,
	  not if COMCONSOLE is defined.
	o Don't call siointr() from comparam() if there is no output in
	  progress.  For the call from sioopen(), there's no output in
	  progress, and siointr() often saw silo overflows for stale
	  input because it was called before sioopen() discarded the
	  input.
	o Let ttselect() do the work for select(), so that the fixes for
	  ttselect() don't have to be duplicated in zillions of drivers.

4cb172d2ef Patch from dcjm@cs.ed.ac.uk (Dave Matthews)...
Yes, I know that IFADDR ioctl is supposed to be deprecated... Note
that the patch was modified by me to fit better into the driver. -DG

...

While porting CAP to 386bsd/pk0.2.4 and now to FreeBSD Release 1.0
I found a couple of bugs associated with the packet filter. Here
are the fixes.  I'm posting them here because they apply to
FreeBSD and 386bsd/pk0.2.4 and possibly to other *BSD.

The first occurs when using the packet filter to write raw
ethernet packets.  The header consisting of the sender and
destination addresses and the protocol is removed and later
added back on, but with the byte order of the protocol reversed.
The fix ensures that the byte order in the protocol field is
swapped when it is removed.

The second fix ensures that SIOCGIFADDR works for BPF as claimed
in the man pages, by adding it to the ed driver.  Similar fixes
will be needed for other ethernet drivers.
Dave Matthews.

4aadf8a7c8 Patch from Brian Smith (modified a little by me) to allow kernel config
file override to disable fifo on 16550s:

I bought a board with two 16550's, but one of those ports has a mouse
on it.  The sio driver always enables the fifo, which is a bad thing
for mice and X.  The mouse is jerky and hard to use.  The simple thing
is be to treat one of the ports as a non-fifo'ed UART, and I use the
flags option in my config file.

So, my config file has:
device      sio0    at isa? port "IO_COM1" tty irq 4 flags 0x2 vector siointr
device      sio1    at isa? port "IO_COM2" tty irq 3 vector siointr

5e2d3df485 VM system performance improvements from John Dyson and myself. The
following is a summary:

1) increased object cache back up to a more reasonable value.
2) removed old & bogus cruft from machdep.c (clearseg, copyseg,
	physcopyseg, etc).
3) inlined many functions in pmap.c
4) changed "load_cr3(rcr3())" into tlbflush() and made tlbflush inline
	assembly.
5) changed the way that modified pages are tracked - now vm_page struct
	is kept updated directly - no more scanning page tables.
6) removed lots of unnecessary spl's
7) removed old unused functions from pmap.c
8) removed all use of page_size, page_shift, page_mask variables - replaced
	with PAGE_ constants.
9) moved trunc/round_page, atop, ptoa, out of vm_param.h and into i386/
	include/param.h, and optimized them.
10) numerous changes to sys/vm/ swap_pager, vnode_pager, pageout, fault
	code to improve performance. LRU algorithm modified to be more
	effective, read ahead/behind values tuned for better performance,
	etc, etc...

875e23d099 Brute-force fix for the "hanging console" problem. Simply _don't_ call
the device close routine. This works because the device close calls
the line discipline close (which only flushes the output buffers) and
the ttyclose() routine, which does little of nothing except screw with
the session and process group fields (which is what was causing all
the problems).

de0ef367ba Removed some more old unused code/comments. Added hack to "fix" the
problem with some chipsets (UMC) remapping the 'hole' memory even when
you've got 16MB. People were led to believe that since there was only
16MB of memory in the machine, that they were okay wrt the ISA DMA
limit. This hack simply causes the extra memory to be ignored if it
appears around the 16MB limit.
