46aa3347cb Convert all users of fldoff() to offsetof(). fldoff() is bad
because it only takes a struct tag which makes it impossible to
use unions, typedefs etc.

Define __offsetof() in <machine/ansi.h>

Define offsetof() in terms of __offsetof() in <stddef.h> and <sys/types.h>

Remove myriad of local offsetof() definitions.

Remove includes of <stddef.h> in kernel code.

NB: Kernelcode should *never* include from /usr/include !

Make <sys/queue.h> include <machine/ansi.h> to avoid polluting the API.

Deprecate <struct.h> with a warning.  The warning turns into an error on
01-12-2000 and the file gets removed entirely on 01-01-2001.

8088699f79 - Overhaul the software interrupt code to use interrupt threads for each
type of software interrupt.  Roughly, what used to be a bit in spending
  now maps to a swi thread.  Each thread can have multiple handlers, just
  like a hardware interrupt thread.
- Instead of using a bitmask of pending interrupts, we schedule the specific
  software interrupt thread to run, so spending, NSWI, and the shandlers
  array are no longer needed.  We can now have an arbitrary number of
  software interrupt threads.  When you register a software interrupt
  thread via sinthand_add(), you get back a struct intrhand that you pass
  to sched_swi() when you wish to schedule your swi thread to run.
- Convert the name of 'struct intrec' to 'struct intrhand' as it is a bit
  more intuitive.  Also, prefix all the members of struct intrhand with
  'ih_'.
- Make swi_net() a MI function since there is now no point in it being
  MD.

someone staticized things in cam_xpt.c.  (That particular problem would

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.

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.
