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.
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.
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
. ``doconfig'' can be written
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.
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.
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 ?".
else has been probed. This feature could go away again, if we can curb the
problem another way.
if_ed.c, syscons.c: Set the above flag. ed# because it needs it, syscons
because it looks stupid to "detect" the display you have already filled up
with text :-)
bt742a.c: Check bt_cmd() return-val during probe, thus failing on adaptec's.
Also silenced various printf's during the probe.
isa.c: Probe devices with the above flag set before the rest. Reduce the
number of "conflict" messages per device to one.

Please test the GENERIC-kernel now, if nobody can make it fail, GENERICAH
and GENERICBT has a finite and short life-expectancy...

I have put it here, because I belive we could share some code among the
various kinds of boot-code, whenever we get the time to look at it.

scheme of things, so I've changed them to be more appropriate. page in/ous
are now associated with the pager that did them. Nuked v_fault as the
only fault of interest that wouldn't be already counted in v_trap is a VM
fault, and this is counted seperately.
2) Implemented most of the remaining counters and corrected the counting of
some that were done wrong. They are all almost correct now...just a few
minor ones left to fix.
