bf67b544a2 Pass the slice number of the boot device to the kernel in the previously
unused bitfields for the adaptor and the controller.  It should go in
the bitfield for the partition but that would not be backwards compatible.

9949ebf656 1. BOOTSEG and BOOTSTACK are now set from the Makefile, the boot code has
been relocated to run in the 64k segment at 0x10000 with the stack at
    the top of this segment.  This corrects the problems machines with 512K
    base memory had booting.

2.  startprog routing rewritten to convert the BOOTSEG ss to a KERNELSEG
    ss, this eliminated the last of the >512K memory references.  Additional
    cleanup in here included a better way to copy the arguments to the
    kernel stack.

3.  Elimination of argv and esym cruft saved a few bytes.

4.  Only need to truncate the head.a_entry to a meg boundary once intead
    of every time we used it!  [Saving more bytes].

5.  Addition of version 1 bootinfo structure support.  These boot blocks
    pass the kernel name in to the kernel now.

6.  Removed historical comments about MACH argv stuff, as it is useless now.

12fafb2d5a 1. Completely rewritten Makefile that uses bsd.prog.mk more effectively.
2.  Clean up the .S files to use /* */ style comments.

This is a totally cosmetic change, not one byte of the resulting boot
code changes.  But at least it is installed with correct owners and in
the right places, and gets recompiled correctly when things change!

b95ed23990 Fixed bootblocks to work with FreeBSD 2.0
1) Fixed up some header locations
2) Replaced list of boot files with /kernel
3) Changed disklabel use in Makefile to conform to 4.4
4) Added size command in Makefile to get close estimate of bootblock
   sizes. Total size of text and data must be below 64K, slightly
   overestimated since a.out header subsequently gets stripped.
5) Various buffer sizes are set to 8192 bytes in sys.c. In 4.4 MAXBSIZE
   is set to 64K which is too big for the bootblocks to deal with.

1c28e35f68 Commit a whole cluster of last minute critical (and one cosmetic) fixes
from David Greenman, Bruce Evans and Julian Elischer.

They are:

[vnode pager - David/Bruce]:
  The following patch fixes a problem where some data could be lost in a
delayed-write buffer if the cached buffer was larger than a page. This fix was
provided by Bruce Evans and modified slightly by me.

[st.c - Julian]:
  My fix for "bad request, must be between 0 and 0"

RTFS if you're interested).

[gnu/fpemul - David/Bruce]:
  These changes fix single stepping of emulated FPU instructions.
Previously, the instruction after an emulated instruction was
executed without causing a SIGTRAP ...

The also fix the initial control word being different for the
GPL emulator (it is still wrong for the old emulator) and remove
an unnecessary panic when emulation is not configured (I hope at
least init, sh and reboot will run without floating point.  I
remember only df and mkfs being broken by the lack of FP in 0.0).

[Various fixes described below - Bruce/David]:
sys/i386/boot/boot2.S:
        Yet another attempt to propagate the correct fix for 16 vs
        32-bit mode bugs.  [verified]

sys/i386/i386/db_interface.c:
        Protect against reentering Debugger().

sys/kern/kern_time.c:
        Don't allow 'time.tv_usec == 0' except at clock interrupts.

sys/pcfs/pcfs_fat.c:
        Make it compile without -O.

sys/scsi/sd.c:
        Fix as posted to some freebsd mailing list.
        (changes the order of the assignment of "sectors" because it earlier
          value is needed first -DG)

sys/vm/vm_glue.c:
        Fix stale comments and verbose code.

sys/vm/vm_mmap.c
        Fix off by 1 errors and verbose code.

[From Nate - cosmetic but non-intrusive and useful enough to go in]
sys/i386/isa/isa.c:
Appended you'll find a patch to the NMI error log routine in isa/isa.c.
The below patch just adds some additional information when an NMI occurs

Subject: cache botch in bootstrap
Date: Sun, 20 Feb 94 18:14:35 +1100
The cache in the bootstrap loader didn't allow for the device changing.

This caused surprisingly little trouble - the cache is only for a single
track (or part of a track), and the first access to a new device is
always for an early sector, so there is no problem unless the last access
to the old device was for an early sector.  I saw the problem on a system
with BSD on wd1 and no label on wd0.  Everything worked if the the device
name wd(1,a) was specified before the default of wd(0,a) was tried, but
when the default was tried, it failed on the first sector because there
was no label, and then the first sector on wd0 was always used instead
of the first sector on wd1, so there was apparently no label on wd1
either.
