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'.
libcam/Makefile:	Add scsi_da.c to libcam for the new
			scsi_format_unit() function.

camcontrol.8:		Update the man page for the new format
			functionality, and take out the examples section
			describing how to do it with 'camcontrol cmd'.

camcontrol.c:		New format functionality.  Note that unlike the
			rest of the camcontrol subcommands, this one is
			interactive by default.  Because of the potential
			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
			is using it.  If that changes, it should be
			un-ifdefed and compiled in both cases.

scsi_da.h:		New function declaration, CDB structure and format
			data structures.

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.

A lot of this patch were machine generated (Thanks to style(9) compliance!)

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.

scsi_all.c:		Add a comment about SHORT_INQUIRY_LENGTH being the
			minimum amount of data needed for
			scsi_print_inquiry() to function.
