1ce407b675 Change the preemption code for software interrupt thread schedules and
mutex releases to not require flags for the cases when preemption is
not allowed:

The purpose of the MTX_NOSWITCH and SWI_NOSWITCH flags is to prevent
switching to a higher priority thread on mutex releease and swi schedule,
respectively when that switch is not safe.  Now that the critical section
API maintains a per-thread nesting count, the kernel can easily check
whether or not it should switch without relying on flags from the
programmer.  This fixes a few bugs in that all current callers of
swi_sched() used SWI_NOSWITCH, when in fact, only the ones called from
fast interrupt handlers and the swi_sched of softclock needed this flag.
Note that to ensure that swi_sched()'s in clock and fast interrupt
handlers do not switch, these handlers have to be explicitly wrapped
in critical_enter/exit pairs.  Presently, just wrapping the handlers is
sufficient, but in the future with the fully preemptive kernel, the
interrupt must be EOI'd before critical_exit() is called.  (critical_exit()
can switch due to a deferred preemption in a fully preemptive kernel.)

I've tested the changes to the interrupt code on i386 and alpha.  I have
not tested ia64, but the interrupt code is almost identical to the alpha
code, so I expect it will work fine.  PowerPC and ARM do not yet have
interrupt code in the tree so they shouldn't be broken.  Sparc64 is
broken, but that's been ok'd by jake and tmm who will be fixing the
interrupt code for sparc64 shortly.

33d2e7c7bc Bring the probe inquiry code in line with the SCSI spec.
It is legal to have a device with device type 0x1f, that just means
that the device is of unknown type.  Instead, only check the peripheral
qualifier when deciding whether or not to reject a device based on its
inquiry information.

24c4b1e75b Rewrite of the CAM error recovery code.
Some of the major changes include:

	- The SCSI error handling portion of cam_periph_error() has
	  been broken out into a number of subfunctions to better
	  modularize the code that handles the hierarchy of SCSI errors.
	  As a result, the code is now much easier to read.

	- String handling and error printing has been significantly
	  revamped.  We now use sbufs to do string formatting instead
	  of using printfs (for the kernel) and snprintf/strncat (for
	  userland) as before.

	  There is a new catchall error printing routine,
	  cam_error_print() and its string-based counterpart,
	  cam_error_string() that allow the kernel and userland
	  applications to pass in a CCB and have errors printed out
	  properly, whether or not they're SCSI errors.  Among other
	  things, this helped eliminate a fair amount of duplicate code
	  in camcontrol.

	  We now print out more information than before, including
	  the CAM status and SCSI status and the error recovery action
	  taken to remedy the problem.

	- sbufs are now available in userland, via libsbuf.  This
	  change was necessary since most of the error printing code
	  is shared between libcam and the kernel.

	- A new transfer settings interface is included in this checkin.
	  This code is #ifdef'ed out, and is primarily intended to aid
	  discussion with HBA driver authors on the final form the
	  interface should take.  There is example code in the ahc(4)
	  driver that implements the HBA driver side of the new
	  interface.  The new transfer settings code won't be enabled
	  until we're ready to switch all HBA drivers over to the new
	  interface.

src/Makefile.inc1,
lib/Makefile:		Add libsbuf.  It must be built before libcam,
			since libcam uses sbuf routines.

libcam/Makefile:	libcam now depends on libsbuf.

libsbuf/Makefile:	Add a makefile for libsbuf.  This pulls in the
			sbuf sources from sys/kern.

bsd.libnames.mk:	Add LIBSBUF.

camcontrol/Makefile:	Add -lsbuf.  Since camcontrol is statically
			linked, we can't depend on the dynamic linker
			to pull in libsbuf.

camcontrol.c:		Use cam_error_print() instead of checking for
			CAM_SCSI_STATUS_ERROR on every failed CCB.

sbuf.9:			Change the prototypes for sbuf_cat() and
			sbuf_cpy() so that the source string is now a
			const char *.  This is more in line wth the
			standard system string functions, and helps
			eliminate warnings when dealing with a const
			source buffer.

			Fix a typo.

cam.c:			Add description strings for the various CAM
			error status values, as well as routines to
			look up those strings.

			Add new cam_error_string() and
			cam_error_print() routines for userland and
			the kernel.

cam.h:			Add a new CAM flag, CAM_RETRY_SELTO.

			Add enumerated types for the various options
			available with cam_error_print() and
			cam_error_string().

cam_ccb.h:		Add new transfer negotiation structures/types.

			Change inq_len in the ccb_getdev structure to
			be "reserved".  This field has never been
			filled in, and will be removed when we next
			bump the CAM version.

cam_debug.h:		Fix typo.

cam_periph.c:		Modularize cam_periph_error().  The SCSI error
			handling part of cam_periph_error() is now
			in camperiphscsistatuserror() and
			camperiphscsisenseerror().

			In cam_periph_lock(), increase the reference
			count on the periph while we wait for our lock
			attempt to succeed so that the periph won't go
			away while we're sleeping.

cam_xpt.c:		Add new transfer negotiation code.  (ifdefed
			out)

			Add a new function, xpt_path_string().  This
			is a string/sbuf analog to xpt_print_path().

scsi_all.c:		Revamp string handing and error printing code.
			We now use sbufs for much of the string
			formatting code.  More of that code is shared
			between userland the kernel.

scsi_all.h:		Get rid of SS_TURSTART, it wasn't terribly
			useful in the first place.

			Add a new error action, SS_REQSENSE.  (Send a
			request sense and then retry the command.)
			This is useful when the controller hasn't
			performed autosense for some reason.

			Change the default actions around a bit.

scsi_cd.c,
scsi_da.c,
scsi_pt.c,
scsi_ses.c:		SF_RETRY_SELTO -> CAM_RETRY_SELTO.  Selection
			timeouts shouldn't be covered by a sense flag.

scsi_pass.[ch]:		SF_RETRY_SELTO -> CAM_RETRY_SELTO.

			Get rid of the last vestiges of a read/write
			interface.

libkern/bsearch.c,
sys/libkern.h,
conf/files:		Add bsearch.c, which is needed for some of the
			new table lookup routines.

aic7xxx_freebsd.c:	Define AHC_NEW_TRAN_SETTINGS if
			CAM_NEW_TRAN_CODE is defined.

sbuf.h,
subr_sbuf.c:		Add the appropriate #ifdefs so sbufs can
			compile and run in userland.

			Change sbuf_printf() to use vsnprintf()
			instead of kvprintf(), which is only available
			in the kernel.

			Change the source string for sbuf_cpy() and
			sbuf_cat() to be a const char *.

			Add __BEGIN_DECLS and __END_DECLS around
			function prototypes since they're now exported
			to userland.

kdump/mkioctls:		Include stdio.h before cam.h since cam.h now
			includes a function with a FILE * argument.

ff18363a3e - 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.

bb27208af1 Add a hack to cam that makes the cam_xpt available to the rest of the
kernel. Justin agress that there is no other reasonable alternative to
do automatic rescans on connect.

The problem is that when a new device attaches to a SIM (SCSI host
controller) we need to send a XPT_SCAN_BUS command to the SIM using
xpt_action. This requires however that there is a peripheral available
to take the command (otherwise xpt_done and later bomb). The RESCAN
ioctl uses the same periph.

This enables a USB mass storage drive to do an automatic rescan on
connection of the drive.

The automatic dropping of a CAM entry on disconnection was already
working (asynchronous event).

The next thing to do is find someone to commit a change to vpo to do the
same thing. Just port umass_cam_rescan and friends across to that
driver.
