9858fcda2e Update comments to routines in vm_page.c, most especially whether a
routine can block or not as part of a general effort to carefully
    document blocking/non-blocking calls in the kernel.

5a4f8fa5a4 Add a quirk NORRLS (no reserve/release) which can (and
will) get set for the devices that don't actually support
reserve/release (so we don't keep trying it).

Add softc storage and manage storing last I/O and CTL
commands that had errors (for correlative purposes).

In saclose clear the 'MOUNTED' bit if we either rewind or
unload (yes, this shouldn't be necessary since the next open
should catch whether a tape change occurred, but I'm having
some questions about that actually working so this is
safer for the moment). Oh, forgot to mention in previous
commit messages that some of the failures particularly at
close time cause the tape to be ejected (for the sake
of safety)- all this prior to redoing the state machine
(which is in progress) which will try and handle this better.

Complete the addition of the setmark support
(from Martin.Birgmeier@aon.at).

capabilities are: AF, AB, cm, ho, me, cd. The code is hidden behind
-DTERM_EMU - should it cause any problems, you can remove this define

You'll find some examples how to use it in src/share/examples/bootforth.

c26abb753a Kill(pid, 0) normally returns 0 on both FreeBSD and Redhat after having
performed all sorts of sanity checks. The FreeBSD linux emulator returns
EINVAL in such a case.
Allowing signal 0 to be passed to kill will result in compatible behaviour.

8194a57215 This is my first cut on a driver for the RealTek RTL 8002 pocket
ethernet driver.

The BUGS section is still impressive, but the driver seems to work for
me now.  Disclaimer: i haven't been able to test this under -current
so far (but it compiles, and the notebook it's intended for can now be
updated to -current more easy than before).  Don't be afraid of the
many #ifdefs on __FreeBSD_version in the imported file; i want them in
the repository on the vendor-branch so other people can also manually
integrate it into older systems.  I'll clean it up on the -current
branch in a followup commit.  The vendor-banch version right now
supports systems back to 2.2R.

This driver should be layered upon ppc(4), but i currently have no
idea how to do this.

Eventually i'll further develop the driver to also support the more
modern RTL 8012 success, which seems to be present in a number of
cheap pocket ethernet adapters these days.  Right now, i doubt it will
run with the 8012 without any changes.

Finally a big Thanks! to RealTek for promptly providing me with
documentation and with the source code for the 8012 pocket driver upon
request.  I wish all vendors were that cooperative!.

3d89c2cdb2 Regrettably, you can't take setdef0.c out of order, or, surprise,
linker sets don't work and thus neither does the kernel.

This should stop being a problem with an improved linker set mechanism in
the pipeline (see the bootloader) but for now this has to stay like this.

990635d6e8 1) Fix some serious bugs (1 botch on my part which caused a filemark to be
written even it the tape was opened readonly- 2 botches in deferred error
handling for FIXED LENGTH mode which caused panic && hand resp.). Fixed
a memory leak in sa_mount.
2) Fixed an annoying bug when turning of compression to actually reflect
this for future status calls.
3) Implement the MTIOCERRSTAT call where latched control and I/O residuals
and sense data are returned to the application asking for them.

3bc124d470 Wait for channel commands to complete after issuing the commands.
The optimisation of only waiting before issuing new commands is
obviously invalid in general and it caused many errors in NIST-PCTS.
I think the errors were mostly for characters sent with the wrong
parity, etc., after a half complete tcsetattr().

Use microtime() instead of a magic loop count to limit the wait.
The wait is a busy-wait :-( and normally takes about 500 usec.
