9d12c4da86 Give up early for empty partitions. The offset for an empty
partition is 0, which is outside the slice unless the disk is
dangerously dedicated.  There is little error checking later, and
following garbage metadata outside the slice usually caused crashes,
Empty 'a' partitions are fairly easy to create by cloning the label
for the whole disk.

Fixed a missing newline in a related error message.

fb5831565c 1) Implement SIOCSIFMTU in ether_ioctl(), and change ether_ioctl's return
type to be int so that errors can be returned.
2) Use the new SIOCSIFMTU ether_ioctl support in the few drivers that are
   using ether_ioctl().
3) In if_fxp.c: treat if_bpf as a token, not as a pointer. Don't bother
   testing for FXP_NTXSEG being reached in fxp_start()...just check for
   non-NULL 'm'. Change fxp_ioctl() to use ether_ioctl().

flag that is used to indicate building LKMs will have be be substituted
in the future.  This allows proper selection of the usage of the
efficient, single instruction in the kernel, but alas, doesn't allow
for use in userland or LKMs :-(.  Them's the breaks!!!

66f61b8256 Change endian.h so that when a kernel is compiled without I386_CPU, and
with one of the following (I486_CPU,I586_CPU,I686_CPU) so it can take
advantage of the very quick bswap insn.  This keeps LKMs from being
built to take advantage of the insn, but also makes sure that the LKMs
can be run on all CPUs.  (The LKMs don't pick up the CPU options :-( ).

cdc2c29161 Make vm_map_insert much more intelligent in the MAP_NOFAULT case so
that map entries are coalesced when appropriate.  Also, conditionalize
some code that is currently not used in vm_map_insert.  This mod
has been added to eliminate unnecessary map entries in buffer map.

Additionally, there were some cases where map coalescing could be done
when it shouldn't.  That problem has been resolved.

96b2533ed1 Bump maximum username length to 16 characters. This brings us into
line with BSD/OS and Linux's username limits, making transitioning from

This is not for 2.2!  This needs to get shaken out longer term in 3.0.

673f8923d0 PR kern/2141:
function ed_attach_NE2000_pci() in if_ed.c passes
        an uninitialized block of memory (got with malloc())
        to ed_attach. This prevents a proper initialization

2/ allow the tsleep() when reading, to be interruptable by signals
so that one can now do:
od -xc </dev/tun0
to dump packets for debugging without getting hung.

1f9d9075e4 Alot of fixes from kazu:
1. All the suggestions earlier made by Bruce: renaming some symbols,
stricter error checking, removing redundant code, etc.

2. The `psm' driver preserves the default counter resolution and
report rate, whatever they are after reset. (Based on reports and
suggestion from Nate and Rob Bolin).

3. The `psm' driver now does not check the so-called sync. bit in the
first byte of the data packet by default, so that the tapping feature
of ALPUS GlidePoint works (based on reports from Louis Mamakos). I
tested the code with ALPUS Desktop GlidePoint (M/N GP101) and found
no problem; tapping worked. It appears ALPUS produces several models
of GlidePoint. I hope the other models are OK too.

The check code can still be activated by defining the PSM_CHECKSYNC
option in the config file. (The bit checking slightly reduces, if not
completely eliminates, weird mouse behavior cased by unsynchronized
mouse data packets. It also helps us to detect if the mouse interrupt
can ever be lost. But, well, if there are devices which cannot be
supported this way...)

4. The `psm' driver does not include the protocol emulation code by
default. The code can still be compiled in if the PSM_EMULATION option
is specified in the config file. Louis Mamakos suggests the emulation
code is putting too much in the kernel, and `moused' works well.
I will think about this later and decide if the entire emulation
code should be removed.

5. And, of course, the fix in `scprobe()' from Bruce to cure the
UserConfig problem. My code in `kbdio.c' is slightly different from
his patch, but has the same effect. There still is a possibility that
`scprobe()' gets confused, if, for whatever reasons, the user holds
down a key for very long time during the boot process. But we cannot
cope with everything, can we?

Most of the standard utilities that depended on (or were broken in

increased the size of buffer_map to the point where the system would

7cb29d3394 This update adds the support for != 512 byte sector SCSI devices to
the sd & od drivers. There is also slight changes to fdisk & newfs
in order to comply with different sectorsizes.
Currently sectors of size 512, 1024 & 2048 are supported, the only
restriction beeing in fdisk, which hunts for the sectorsize of
the device.
This is based on patches to od.c and the other system files by
John Gumb & Barry Scott, minor changes and the sd.c patches by
me.
There also exist some patches for the msdos filesys code, but I
havn't been able to test those (yet).

79c2a5b3ff Cosmetic code cleanup from Matt's latest driver.
a)  Removal of private typedefs tulip_uint*_t, use standard u_int_*_t.

b)  Change [Dd][Cc]21.4. to just 21.4., seems Dec has done this to all
    of the drivers for all OS's.  (Did they get in trouble with someone?)
    [The few that remain can either not be eliminated, or are waiting for
    additional driver functional changes that will remove them.]

c)  Move some code from dc21040.h into the driver, later a whole block of that
    code and more will move to devar.h, but for now this makes it easier
    to study diffs.

d)  Add a big bold comment to the README.de file about it not reflecting
    reality anymore.

Note that these are all cosmetic changes and should be no functional
change in the driver whatsoever.  If _anyone_ spots a problem introduced
by this please let me know ASAP!

09e0c6ccdd Implement a new totally dynamic (up to MAXPHYS) buffer kva allocation
scheme.  Additionally, add the capability for checking for unexpected
kernel page faults.  The maximum amount of kva space for buffers hasn't
been decreased from where it is, but it will now be possible to do so.

This scheme manages the kva space similar to the buffers themselves.  If
there isn't enough kva space because of usage or fragementation, buffers
will be reclaimed until a buffer allocation is successful.  This scheme
should be very resistant to fragmentation problems until/if the LFS code
is fixed and uses the bogus buffer locking scheme -- but a 'fixed' LFS
is not likely to use such a scheme.

Now there should be NO problem allocating buffers up to MAXPHYS.
