b0f62f0c1c Add quirk entries from Andre Albsmeier to disable the sync cache command
for the Quantum "MAVERICK 540S" and "LPS525S".

Also, add common string variables, since we seem to have a few Quantum and
Micropolis drives in here.

Fix the 'quantum' variable usage in scsi_all.c that likely got broken when
someone staticized things in cam_xpt.c.  (That particular problem would
cause Quantum Fireball ST drives to not get spun up if they were not
already spinning.)

36875740cc Don't attempt to actually read SAF-TE temperature objects- nobody seems
to be obeying the original spec as to what the numeric value means.

Temperature flags are unaffected- these are still the 'pseudo-thermometers'
and overtemp/undertemp warnings will be caught and translated to SES objects
here.

7e32b20d95 This is an overhaul of the mode page handling in camcontrol as well as
related patches. These include:
	* Mode page editting can be scripted. This involves two
	  things: first, if stdin is not a tty, changes are read from
	  stdin rather than invoking $EDITOR. Second, and more
	  importantly, not all modepage entries must be included in the
	  change set. This means that camcontrol can now gracefully handle
	  more intrusive editting from the $EDITOR, including removal or
	  rearrangement of lines. It also means that you can do stuff
	  like:
		# echo "WCE: 1" | camcontrol modepage da3 -m 8 -e
		# newfs /dev/da3
		# echo "WCE: 0" | camcontrol modepage da3 -m 8 -e
	* Range-checking on user-supplied input values. modeedit.c now
	  uses the field width specifiers to determine the maximum
	  allowable value for a field. If the user enters a value larger
	  than the maximum, it clips the value to the max and warns the
	  user. This also involved patching cam_cmdparse.c to be more
	  consistent with regards to the "count" parameter to arg_put
	  (previously is was the length of strings and 1 for all integral
	  types). The cam_cdbparse(3) man page was also updated to reflect
	  the revised semantics.
	* In the process, I removed the 64 entry limit on mode pages (not
	  that we were even close to hitting that limit). This was a nice
	  side-effect of the other changes.
	* Technically, the new mode editting functionality allows editting
	  of character array entries in mode pages (type 'c' or 'z'),
	  however since buff_encode doesn't grok them it is currently
	  useless.
	* Camcontrol gained two new options related to mode pages: -l and
	  -b. The former lists all available mode pages for a given
	  device. The latter forces mode page display in binary format
	  (the default when no mode page definition was found in
	  scsi_modes).
	* Added support for mode page names to scsi_modes. Allows names to
	  be displayed alongside mode numbers in the mode page
	  listing. Updated scsi_modes to use the new functionality. This
	  also adds the semicolon into the scsi_modes syntax as an
	  optional mode page definition terminator. This is needed to name
	  pages without providing a page format definition.
	* Updated scsi_all.h to include a structure describing mode page
	  headers.
	* Added $FreeBSD$ line to scsi_modes.

d082442a09 Apply a `fixup' to the blocksize gathered from the device after a READ
CAPACITY operation.  SCSI-3 mandates this to be 2048, but some older
drives like my old Plasmon CD-R report weird numbers between 2048 and
up to 2352 bytes depending on the mode of the last track etc.  This in
turn confuses stuff like the slice code since it refuses to work with
devices that do not have a blocksize which is a multiple of 512 bytes.

96a93c63a8 Implement a new camcontrol function, 'camcontrol format'.

camcontrol.8:		Update the man page for the new format
			functionality, and take out the examples section

camcontrol.c:		New format functionality.  Note that unlike the

			destructiveness of the format command, I thought
			it necessary to get confirmation from the user
			before spamming a disk.  You can disable the
			interactive behavior, and the status meter with
			command line arguments.

scsi_da.c:		Add the new scsi_format_unit() cdb building
			function and use #ifdef _KERNEL to make this file
			compile in both the kernel and userland.  The
			format unit function is currently only defined in
			the non-kernel case, because nothing in the kernel

0385347c1a Implement an optimization of the VM<->pmap API. Pass vm_page_t's directly
to various pmap_*() functions instead of looking up the physical address
and passing that.  In many cases, the first thing the pmap code was doing
was going to a lot of trouble to get back the original vm_page_t, or
it's shadow pv_table entry.

Inspired by: John Dyson's 1998 patches.

Also:
Eliminate pv_table as a seperate thing and build it into a machine
dependent part of vm_page_t.  This eliminates having a seperate set of
structions that shadow each other in a 1:1 fashion that we often went to
a lot of trouble to translate from one to the other. (see above)
This happens to save 4 bytes of physical memory for each page in the
system.  (8 bytes on the Alpha).

Eliminate the use of the phys_avail[] array to determine if a page is
managed (ie: it has pv_entries etc).  Store this information in a flag.
Things like device_pager set it because they create vm_page_t's on the
fly that do not have pv_entries.  This makes it easier to "unmanage" a
page of physical memory (this will be taken advantage of in subsequent
commits).

Add a function to add a new page to the freelist.  This could be used
for reclaiming the previously wasted pages left over from preloaded
loader(8) files.

21144e3bf1 Remove B_READ, B_WRITE and B_FREEBUF and replace them with a new
field in struct buf: b_iocmd.  The b_iocmd is enforced to have
exactly one bit set.

B_WRITE was bogusly defined as zero giving rise to obvious coding
mistakes.

Also eliminate the redundant struct buf flag B_CALL, it can just
as efficiently be done by comparing b_iodone to NULL.

Should you get a panic or drop into the debugger, complaining about
"b_iocmd", don't continue.  It is likely to write on your disk
where it should have been reading.

This change is a step in the direction towards a stackable BIO capability.

955f7e7474 Fix 'camcontrol inquiry'. The inquiry data structure changes (increased to
256 bytes) caused it to break on many devices.

The SCSI spec says that for commands with 8-bit length fields, a value of 0
means 256 bytes.  As it turns out, many devices don't deal with that
properly.  Some interpret the 0 as 0, and return no data.  Others return
more than 256 bytes of data, and cause an overrun.

The fix is to tell the device we've only allocated SHORT_INQUIRY_LENGTH (36
bytes) of inquiry data, instead of sizeof(struct scsi_inquiry_data).

camcontrol.c:		Change inq_len in the call to scsi_inquiry() to
			SHORT_INQUIRY_LENGTH, and add a long comment
			explaining the reason for the change.

scsi_all.h:		Add a comment above the definitinon of
			SHORT_INQUIRY_LENGTH alerting people that it is
			both the initial probe inquiry length, and the
			minimum amount of data needed for scsi_print_inquiry()
			to function.

			minimum amount of data needed for
			scsi_print_inquiry() to function.

223b7a2363 Quirk all Pioneer changers as changers up front, instead of waiting for the
second LUN to show up.

mjacob's change (which is correct) in rev 1.21 of cam_periph.c to elminiate
infinite retries of the SCSI busy status bit seems to have broken probing
of Pioneer changers that aren't already quirked.

The right way to fix this is probably to change things around so we can
guarantee 100% sequential probing of LUN-based changers even if they aren't
quirked.  This should fix things for now, though.

Also, the 'CCD' priority is now the 'ARRAY' priority, and a number of
drivers have been modified to use that priority.

This includes the necessary changes to all drivers, except the ATA drivers.
Soren will modify those separately.

This does not include and does not require any change in the devstat
version number, since no known userland applications use the priority

ddc83e8523 Don't clear the SA_FLAG_TAPE_LOCKED prior to calling
saprevent when we're doing an OFFLINE ioctl- saprevent
won't unlock the door, which then causes the unload to
fail on some units.

If we've already unloaded the tape, don't try and rewind and
unload in saclose. This is a slightly riskier change because
we're now going to depend on SA_FLAG_TAPE_MOUNTED to say whether
we've really unloaded the tape. This involved changing the
setting in sadone for tape errors to SA_FLAG_TAPE_FROZEN (which
is more accurate anyway-if you get an EIO you've probably lost
tape position anyway) where it used to just clear the mounted
flag.

Merge the contents (less some trivial bordering the silly comments)

the #defines for the vm_inherit_t and vm_prot_t types next to their

This paves the road for the commit to follow shortly: change
useracc() to use VM_PROT_{READ|WRITE} rather than B_{READ|WRITE}
as argument.

Diskslice/label code not yet handled.

Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers)

Add the correct hook for devfs to kern_conf.c

The net result of this excercise is that a lot less files depends on DEVFS,
and devtoname() gets more sensible output in many cases.

A few drivers had minor additional cleanups performed relating to cdevsw
registration.

A few drivers don't register a cdevsw{} anymore, but only use make_dev().

3ece1bd296 Fix short timeout problems with the pt(4) driver:
- increase the default timeout from 10 seconds to 60 seconds
- add a new kernel option, SCSI_PT_DEFAULT_TIMEOUT, that lets users specify
  the default timeout for the pt driver to use
- add two new ioctls, one to get the timeout for a given pt device, the
  other to set the timeout for a given pt device.  The idea is that
  userland applications using the device can set the timeout to suit their
  purposes.  The ioctls are defined in a new header file, sys/ptio.h

printf("%x", dev) now becomes printf("%s", devtoname(dev)) because

printing a pointer to an address that would never help the developer debug.

Handle errors reported through immediate notify ccbs.  This includes
bus resets, BDR messages, and abort messages.

in data phases, reselection failure, and IDE message received.

Add a mechanism for stalling the queue of transactions to a particular
initiator while a CA is in progress.  Since we don't yet support
tagged I/O, this is largely just for show right now.

2447bec829 Simplify cdevsw registration.
The cdevsw_add() function now finds the major number(s) in the
struct cdevsw passed to it.  cdevsw_add_generic() is no longer
needed, cdevsw_add() does the same thing.

cdevsw_add() will print an message if the d_maj field looks bogus.

Remove nblkdev and nchrdev variables.  Most places they were used
bogusly.  Instead check a dev_t for validity by seeing if devsw()
or bdevsw() returns NULL.

Move bdevsw() and devsw() functions to kern/kern_conf.c

Bump __FreeBSD_version to 400006

This commit removes:
        72 bogus makedev() calls
        26 bogus SYSINIT functions

Add HP T20* Travan-5 like tape device as a FIXED/512 type device.
Works for me. Add TANDBERG SLR5 as a variable SA_QUIRK_1FM device.
Change VIPER 2525 to 1024 byte blocksize. It's possible other
drives should change too, but see below..

Change argument to sagetparams to be pointer to a sa_comp_t union-
this can be either a DATA COMPRESSION or a DEVICE CONFIGURATION
page. In general compression now tries to use the DATA COMPRESSION
page and if that fails tries the DEVICE CONFIGURATION page.

Change close routine to not rewind tape if there's a failure in either
writing filemarks or in backing over one of two filemarks for a 2FM
at EOT tape- instead mark the tape as 'frozen' and print a message
saying that either an OFFLINE or REWIND or an MTEOM command is needed
to clear this state (all bring certainty back to tape position). Fix
sastrategy to not allow I/O to a frozen tape.

Add MTIOCGETEOTMODEL/MTIOCSETEOTMODEL ioctls that get and set the EOT
model for a tape drive (you can now dynamically change whether it's
a 2 FM @ EOT or 1FM at EOT tape device). This ought to give folks
something to handle the QIC drives we don't know about. Correctly propagate
record of compression algorithm back. Clear FROZEN flag for EOM, REWIND
and OFFLINE (and RETENSION and ERASE) cases.

Fix an egregious bug in sadone that had left the device queue frozen
for deferred (for fixed mode case) errors.

Add comment in samount about how useless the test unit ready is for
invalidating a mount (this has to be fixed later).

Fix residual calculation (per Eivind) in saerror so that negative values
for tape records being too large for the supplied buffer get caught. Do
some other saerrro cleanup.
