c2c92de148 Tweak the data/bss segment page count. The last version worked
with all the test cases I tried, I'm sure this is more correct.

Tweak some prototypes.

83a82ed770 Fix the vm_map_remove and vm_map_protect calls.. Somewhere along the
line, these had got (start, length) arguments instead of (start, end)
args.  This could be the cause of Robert Sanders lockups with ZMAGIC
binaries.

c1675b0847 Implement rudumentry support for the linux TIOC[SG]ETSERIAL ioctl's.
To complete this, some extra state has to be kept somewhere so that the
B38400 flag in Linux can be correctly translated to/from either 38400,
57600 or 115200.

f7d16bb60b Fix the getdents() emulation, the Linux ELF libraries use this, and
this code was not quite right (linux has a readdir and getdents syscall,
with the same args. readdir only returns one entry and uses a mutant
dirent structure.  This code was also returning the mutant form for
getdents as well.  My fault for missing this before.)

7d151a09c3 First attempt at FreeBSD & Linux ELF support.
Compile and link a new kernel, that will give native ELF support, and
provide the hooks for other ELF interpreters as well.

To make native ELF binaries use John Polstras elf-kit-1.0.1..
For the time being also use his ld-elf.so.1 and put it in
/usr/libexec.

The Linux emulator has been enhanced to also run ELF binaries, it
is however in its very first incarnation.
Just get some Linux ELF libs (Slackware-3.0) and put them in the
prober place (/compat/linux/...).
I've ben able to run all the Slackware-3.0 binaries I've tried
so far.
(No it won't run quake yet :)

Cleanse the SCSI subsystem of its internally defined types
	u_int32, u_int16, u_int8, int32, int16, int8.
	Use the system defined *_t types instead.

aic7xxx.c:
	Fix the reset code.
	Instead of queing up all of the SCBs that timeout during timeout
	processing, we take the first and have it champion the effort.
	Any other scbs that timeout during timeout handling are given
	another lifetime to complete in the hopes that once timeout
	handing is finished, they will complete normally.  If one of
	these SCBs times out a second time, we panic and Justin tries
	again.

	The other major change is to queue flag aborted SCBs during timeout
	handling, and "ahc_done" them all at once as soon as we have the
	controller back into a sane state.  Calling ahc_done any earlier
	will cause the SCSI subsystem to toss the command right back at
	us and the attempt to queue the command will conflict with what
	the timeout routine is trying to accomplish.

	The aic7xxx driver will now respond to bus resets initiated by
	other devices.

residing in a buffer that had been dirtied by a process was being
handled incorrectly.  The pages were mistakenly placed into the
cache queue.  This would likely have the effect of mmaped page modifications

the same locations in a file.

50e6783510 Make user-level PPP on-demand with dynamic IP actually work.
Story so fr:
1) PPP on-demand with static IP works.
2) PPP on-demand with dynamic IP says "Host is down" on any IP request
The problem is that tun driver check its READY state by *first* ifconfig address.
i.e.:
set ifaddr <addr> <addr2>
works (static IP) and
set ifaddr 0 <addr2>
not works (dynamic IP) because first address is equal 0.
Since tun is always POINTOPOINT interface, dst address is more meaningfull.
I change checking to second (dst) address in READY test.
PPP on-demand finally works.

627e1bd585 Made the timeouts in gets() machine-independent. Use the BIOS tick
counter instead of the BIOS time call to save space.

Reworked the anti-noise timeout to avoid duplicating code.  The timeout
in the outer loop is now restarted after every noise timeout, so it is
now possible for the total timeout to be infinite; previously, the maximum
total timeout was 150000 seconds.

6c2def279e Fixed restoring segment descriptors in prot_to_real(). The descriptors
must have limit 0xffff and attribute G = 0 (byte granularity) as well
as other properties that they already had (see e.g., the Intel i486
manual section 22.5).  Not restoring them broke Ctrl-Alt-Del in the
bootstrap for my ASUS P55TP4XE system, probably because the Award BIOS
does anti-tracing stuff involving inaccessible %esp's.

asm.S:
Don't use lret in prot_to_real().  This reduces the risk of using an
incompletely intialized stack segment and saves space.

51a9444d94 Fix a problem in the swap pager that caused some of the pages that
were paged in under low swap space conditions to both loose their
backing store and their dirty bits.  This would cause pages to
be demand zeroed under certain conditions in low VM space conditions
and consequential sig-11's or sig-10's.  This situation was made
worse lately when the level for swap space reclaim threshold was
increased.
