Remove patch kit headers, and add $Id$
This is mostly to align some more code with NetBSD.
cpu.h:
Remove the old function vs. include configuration stuff that was
ifdefed out when we went to inline functions.
Remove the define of resettodr that made it a nop, there is
already a function that makes it a nop, no need to #define one.
Remove the #defines of processor types, they are now defined
in cputypes.h, #include that file.
Add struct cpu_nameclass for support of cpu types.
frame.h:
include sys/signal.h, it will be needed in the future.
put the sigframe structure here that was in machdep.c
pcb.h:
Add multiple inclusion protection.
Add pcb_ldt and pcb_ldt_len to pcb structure, this is for the
user mode ldt.
removed patch kit headers and sccsids, add $Id$. This is a general
clean up and reallignment with NetBSD-current where possible.
genassym.c:
removed extranious include of reg.h
removed old FP_* defines that have been ifdefed out since the patch kit
removed PCB_SIGC that is not referenced anywhere
add trapframe and sigframe defines
add KERNBASE define for use in locore.s
locore.s:
include npx.h and use NNPX for turning on and off FPU
include machine/cputypes.h for the types of cpu (used in cpu_identify)
change SYSPDREND to be one higher, this is really the base of the
next area, and will be changing again next time I revise the file
Reverse the NOP defines, you now get slow NOP's by default, this
may be what is casuing us trouble with some systems. If you want
the NOPS to be null you now need to have options DUMMY_NOPS.
Now get esym from the boot blocks which don't pass it yet, and
it is not used, but this will be changing.
Move the bit_colors stuff to be in with the rest of Bruces SHOW_A_LOT
things for debugging.
Added NetBSD's CPU type probe code, we now know what type of CPU
we are running on.
Adjust kernel pde calcuation to correct for change in SYSPDREND, no
longer need the +1.
machdep.c
include npx.h and use NNPX for turning on and off FPU
include isa.h, map.h(new file), exec.h in preperation for
changes that are still in process.
Add some of the code for MACHINE_NONCONTIG that will alow us
to better map around the BIOS memory area.
Now print the version, cpu id, real memory and availiable memory
during boot.
Correct the calculation of bufpages, the code was mixing pages
and bytes, it now does the right things. Removed Bill's hack
for limiting the erronous calculation.
add the identifycpu print out code from NetBSD.
remove the definition of the sigframe struct, it belongs in
frame.h
put in printf's about syncing disks on a halt/reboot.
Change the halted message to be a little easier reading.
Clean up of the dump messages, makes the source and the output
much more readable.
Change 0,0 in several places to have spaces after the commas.
is so often reported as an error condition when it is not. We print the
size of things so for those who want to know if this happened they can
figure it out from the size information that is printed.
Change the cpu "i386" line to 2 lines:
cpu "I386_CPU"
cpu "I486_CPU"
This is so we can do real CPU classification of code.
Fix missing depend for assym.s which does depend on genassym.c
lines to match NetBSD. Added $Id$.
Added MID_MACHINE from NetBSD.
Removed definition of DELAY() for non-kernel soures.
Fixed some small english errors that had been corrected in NetBSD.
File is now identical to NetBSD's, but will be changing soon for some
of my clean up work.
machdep.o is a defined to be a target in 2 places. This was caused by
the addition of the LOAD_ADDRESS stuff. Removed the extranious target
of machdep.o.
* patch from vak@zebub.msk.su (Serge V.Vakulenko) to work around
* a hardware bug in cheap WD clone boards where the PROM checksum
* byte is always zero
it relocates it to be after the BIOS memory hole instead of right below
the 640K limit.
THANK YOU CHRIS!!!

basically, reserve a new 32k space right after firstaddr,
and put the buffer space there...
the diffs are below, and are in ~cgd/sys/i386/i386 (in machdep.c)
on freefall. i obviously can't test them, so if some of you would
look the diffs over and try them out...

Description:
Old wt driver is too incomplete and buggy.
It does not support Archive controllers, BSD-like
tape ioctls, multiple tape controllers, different
tape density etc.
Fix:
This driver is a replacement of the old one.
It was not tested on different controllers, though.
This is the streamer tape driver for 386bsd and FreeBSD,
which supports Wangtek and Archive controllers.
It was developed as a replacement of the old Wangtek
tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
4) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
5) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
6) Tape density switching added.
7) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.
* Added software NIC reset in NE probe to work around a problem
* with some NE boards where the 8390 doesn't reset properly on
* power-up. Remove initialization of IMR/ISR in the NE probe
* because this is inherent in the reset.
* added no multi-buffer override for 3c503
*
* Revision 2.1 93/09/29 12:32:12 davidg
* changed multi-buffer count for 16bit 3c503's from 5 to 2 after
* noticing that the transmitter becomes idle because of so many
* packets to load.
*
* Revision 2.0 93/09/29 00:00:19 davidg
* many changes, rewrites, additions, etc. Now supports the
* NE1000, NE2000, WD8003, WD8013, 3C503, 16bit 3C503, and
* a variety of similar clones. 16bit 3c503 now does multi
* transmit buffers. Nearly every part of the driver has
* changed in some way since rev 1.30.

To bring this error try to make two swap partitons on one disk:
one of the partitions will be not recognized.
Fix is simple: set uninitialized val variable.
