in the far pointers are multiples of 4K (as is normal when the video
BIOS is at seg 0xc000). Disallow mode switching if the pointer is bad.
Use a new pa_to_va() macro for all BIOS and video addresses in syscons.
that add it too, and end up fighting an unwanted battle right now,
I'm just going to back away from both and start including my own private
copies of everything. I'm not going to use _anything_ from libkern
until we decide its fate.
Changed the fifth parameter to register_intr() from u_int mask into
u_int *maskptr in preparation for new features (shared interrupts and
removable devices, eg. for PCMCIA).

Recommend -Wimplicit in CWARNFLAGS next. There are still a few hundred
potential arg mismatches because no function declaration is in scope.
Don't duplicate option `-I.'.
Remove null editing of the assembler source for all profiled objects.
The required magic has been done since prehistoric times by an
asm("mcount") declaration.
Simplify the clean rule.
Don't try to be clever about timestamps involving genassym. genassym's
timestamp usually got ahead of assym.s's timestamp, so `make' almost
always had to run genassym and compare *assym.s to decide that nothing
needed to be done. The cost is reassembling a few files whenever
genassym is rebuilt. Assembling is almost as fast as comparing.
Always go through genassym.o to build genassym. This would have avoided
numerous bugs involving mkdep -p. Now it just stops genassym from
depending on the name of the temporary object file.
Use ${CFLAGS} for building genassym. Mainly ${CWARNFLAGS} were missing.
I just know I'm going to get flamed for adding for the miserable
abortion that is libkern, but what am I supposed to do? At least I
didn't drag in the ctype stuff! :-)
of memory to work without running out of kernel VM (and increasing it to
even more than it is now (96MB) is out of the question. Changed bufpages
calculation to allocation a little less bufer cache (16% of mem-2MB instead
of 20%); this is simply a better figure for most systems.
text. Fixed rounding bug that caused the last page of kernel text to be
read/write instead of read-only. This is important now that tmpstk can
crash into it. Removed +4 bias of tmpstk because it screws up ddb's
ability to traceback correctly.
and all SCSI devices (except that it's not done quite the way I want). New
information added includes:
- A text description of the device
- A ``state''---unknown, unconfigured, idle, or busy
- A generic parent device (with support in the m.i. code)
- An interrupt mask type field (which will hopefully go away) so that

This requires a new version of the `lsdev' program as well (next commit).
explanation. More doc needed, but not hard to do, if you want to.
A big hand to Martin Renters for the netboot program !
Anybody want to compete on who can "make world" in the shortest
amount of time ? I have 127 i486DX2/66 and 5 P60's I can use
now. And 3 times 66 Gb file servers to support it... :->
Anyway, NFS will be standard in the GENERIC kernel now, so that
people can use the bin-tarball to set up shop.
A word of wisdom, don't do this:
| cd /usr/bin
| for i in *
| do
| cp $i /tmp/a
| gzip -9 < /tmp/a > $i
| done
It will compress files with multiple links several times. do it this way:
| cd /usr/bin
| for i in *
| do
| gunzip -f < $i > /tmp/a
| gzip -9 < /tmp/a > $i
| done
This is part of a bug fix from Kirk McKusick to work around problems in FFS
related to the blkno of a 64bit offset not fitting into an int. Note the
proper solution would be to deal with 64bit block numbers, but doing this
would require sweeping changes; some other day perhaps.

that this is intended for use only in floppy situations and is done at
the sacrifice of performance in that case (in ther words, this is not the
best solution, but works okay for this exceptional situation).

One of the alpha testers (ETO, Toshihisa <eto@osl.fujitsu.co.jp>)
of my APM driver sent me a very small patch to if_ze.c for using IBM
PCMCIA Ethernet card II. There are only a few difference between
Ethernet card I and II. So we can use them both with this patch. It
also includes a patch for PCIC of ThinkPad 230Cs (As long as I
remember, this model is available in Japan only. But it is very
popular subnote in Japan).

so i hope i've finally removed all the occasions where the driver
got stuck when there's no floppy in the drive.
Also attemmpting to omit the error mesage for ``recalib failed''
for the first time, since people tend to be confused about this.
From now on, >all< swapdevices must be activated with "swapon".
If you havn't got it, add this line to /etc/fstab:
/dev/wd0b none swap sw 0 0
ne sec
Reason:
We want our GENERIC* kernels to have a large selection of swap-devices, but
on the other hand, we don't want to use a wd0b as swap when we boot of a
floppy. This way, we will never use a unexpected swapdevice. Nothing else
has changed.
drivers have a chance to change their IRQ before it is checked.
This was implemented in revision 1.21 and broken in revision 1.26.
Drivers that can change their IRQ should probably be configured
with "irq ?".
