d091793974 Ran ft.c through ident.
Added a missing #ifdef INET wrapper in lpt.c

Main change:
	Removed the timeout_func_t casts from timeout calls and
	correctly defined the timeout routines to conform to
	the new format.
lpt.c doesn't have this change.

f540b1065a Change all #includes to follow the current Berkeley style. Some of these
``changes'' are actually not changes at all, but CVS sometimes has trouble
telling the difference.

This also includes support for second-directory compiles.  This is not
quite complete yet, as `config' doesn't yet do the right thing.  You can
still make it work trivially, however, by doing the following:

rm /sys/compile
mkdir /usr/obj/sys/compile
ln -s M-. /sys/compile
cd /sys/i386/conf
config MYKERNEL
cd ../../compile/MYKERNEL
ln -s /sys @
rm machine
ln -s @/i386/include machine

0e195446b7 Bug fixes and performance improvements from John Dyson and myself:
1) check va before clearing the page clean flag. Not doing so was
	causing the vnode pager error 5 messages when paging from
	NFS. (pmap.c)
2) put back interrupt protection in idle_loop. Bruce didn't think
	it was necessary, John insists that it is (and I agree). (swtch.s)
3) various improvements to the clustering code (vm_machdep.c). It's
	now enabled/used by default.
4) bad disk blocks are now handled properly when doing clustered IOs.
	(wd.c, vm_machdep.c)
5) bogus bad block handling fixed in wd.c.
6) algorithm improvements to the pageout/pagescan daemons. It's amazing
	how well 4MB machines work now.

aaf08d94ca Make everything compile with -Wtraditional. Make it easier to distribute
a binary link-kit.  Make all non-optional options (pagers, procfs) standard,
and update LINT to reflect new symtab requirements.

NB: -Wtraditional will henceforth be forgotten.  This editing pass was
primarily intended to detect any constructions where the old code might
have been relying on traditional C semantics or syntax.  These were all
fixed, and the result of fixing some of them means that -Wall is now a
realistic possibility within a few weeks.

16111ced9f Reset fdc during probe.
From: <dec@lazarus.nrtc.northrop.com>
   Changes between EPSILON and RELEASE of FreeBSD have again caused
the kernel to not see my floppy disk drives.  I don't know what happened,
'cause I don't see any changes to fd.c, but here is an old fix that
I have applied to the probe routine which will solve the problem (at
least for me).  Since this is a rather brute-force solution - I understand
if you want to ignore it...

I think removing FINDWORK would make things clearer.

Nothing much is going to start work on the next item.  However, it is
pointless to continue processing the queue for the same unready drive.
Aborting all reads and trying harder to perform all writes would be
better.

The fd driver reported the wrong cylinder/head/sector numbers after an
error (ST3 is only valid after a sense-drive command), and didn't report
fs block numbers (diskerr was not used).

There was an old problem with writes to block fd devices.   Try this:

1. write protect floppy in fd0.
2. tar cf /dev/fd0a /dev/null.  Repeat a few times.  Later writes tend to
   terminate earlier.
   3. un-write protect floppy.
   4. repeat step 2.  The writes tend to return 0, 2048, 4096, ... and then
      succeed.

This was caused by a bug in vfs__bios.c.  (The bug is fixed in NetBSD's
vfs_bio.c.)  fd.c sets bp->b_resid to nonzero after an error.  vfs__bios.c
was not initializing bp->b_resid.  This causes some writes to terminate
early (e.g., writes to block devices; see spec_write()).

Related funnies:

1. Nothing tries to write the residual bytes.
2. The wd driver sets bp->b_resid to 0 after an error, so there's no
   way anything else could write the residual bytes.
3. I use the block fd device for tar because the raw device seemed to
   have more bugs long ago, and because it ought to be able to handle
   buffering more transparently (I don't want to have to know the
   device size).  But spec_write() always uses the size BLKDEV_IOSIZE
   == 2048 which is too small.  For disks it should use the size of
   one track (rounded down to meet the next track boundary or the i/o
   size).  Here it would help if the DIOCGPART ioctl worked.  But
   DIOCGPART is not implemented for floppies, and the disk size is
   ignored except for partitions of type FS_BSDFFS.

dc4ff321f2 Removed $Log$ section and patch kit headers. And here is the full
message for Bruces changes:

>From: bde@kralizec.zeta.org.au (Bruce Evans)
>Subject: fixes for fd driver

I think I've fixed some bugs in the 0.2.4 fd driver.

1. The main cause of hangs was that there was no timeout for seeks.  So
   attempting i/o with no floppy in the drive hung iff a seek was required.

2. Opens of unattached drives were allowed.  The kernel usually paniced
   soon after due to a bad pointer.

3. Some timeout functions ran at splclock() instead of splbio().  This
   may not have mattered.

4. The state machine was left in a funny state after a timeout.

5. Some function headers were new-style.

6. I picked up some code posted the other day to implement label ioctls.
   Now `disklabel fd0' works.  See a comment for how to modify conf.c.

3b3837db61 Fixed poor timeout code in out_fdc. The timeout counter was not being
reinitialized between while loops.  Added comments about what was going
on in the out_fdc routine.

out_fdc now returns if the direction bit is not set in time instead of
trying to wait for MRQ to get cleared.

2a6c898016 Modified attach printf's so that the output is compatible with the "new"
way of doing things. There still remain several drivers that need to
be updated.  Also added a compile-time option to pccons to switch the
control and caps-lock keys (REVERSE_CAPS_CTRL) - added for my personal
sanity.
