Roll minor version. Remove ISP2100_FABRIC define (unneeded now).

Comment out usage of ISP_SMPLOCK- I have my doubts that this works sanely
as yet because CAM itself still needs Giant. I *was* dropping my lock
and grabbing Giant when doing the upcall for completion, but this is all
seems ridiculous until CAM is fixed.

Change and clean the mutex lock interface.

Change and clean the mutex lock interface.

mtx_enter(lock, type) becomes:

mtx_lock(lock) for sleep locks (MTX_DEF-initialized locks)
mtx_lock_spin(lock) for spin locks (MTX_SPIN-initialized)

similarily, for releasing a lock, we now have:

mtx_unlock(lock) for MTX_DEF and mtx_unlock_spin(lock) for MTX_SPIN.
We change the caller interface for the two different types of locks
because the semantics are entirely different for each case, and this
makes it explicitly clear and, at the same time, it rids us of the
extra `type' argument.

The enter->lock and exit->unlock change has been made with the idea
that we're "locking data" and not "entering locked code" in mind.

Further, remove all additional "flags" previously passed to the
lock acquire/release routines with the exception of two:

MTX_QUIET and MTX_NOSWITCH

The functionality of these flags is preserved and they can be passed
to the lock/unlock routines by calling the corresponding wrappers:

mtx_{lock, unlock}_flags(lock, flag(s)) and
mtx_{lock, unlock}_spin_flags(lock, flag(s)) for MTX_DEF and MTX_SPIN
locks, respectively.

Re-inline some lock acq/rel code; in the sleep lock case, we only
inline the _obtain_lock()s in order to ensure that the inlined code
fits into a cache line. In the spin lock case, we inline recursion and
actually only perform a function call if we need to spin. This change
has been made with the idea that we generally tend to avoid spin locks
and that also the spin locks that we do have and are heavily used
(i.e. sched_lock) do recurse, and therefore in an effort to reduce
function call overhead for some architectures (such as alpha), we
inline recursion for this case.

Create a new malloc type for the witness code and retire from using
the M_DEV type. The new type is called M_WITNESS and is only declared
if WITNESS is enabled.

Begin cleaning up some machdep/mutex.h code - specifically updated the
"optimized" inlined code in alpha/mutex.h and wrote MTX_LOCK_SPIN
and MTX_UNLOCK_SPIN asm macros for the i386/mutex.h as we presently
need those.

Finally, caught up to the interface changes in all sys code.

Use the isp_lastmbxcmd tag to report timed out mailbox commands.

Arrrggghhhh! Very likely fix 22650 by remembering to, ahem, set
CAM_AUTOSNS_VALID when one has sense data.

out the mailbox command opcode if the command times out.

Add USEC_SLEEP macro support. Change the location at which we define
ISP_LOCK/ISP_UNLOCK macros.

Get rid of ridiculous ISP_PVS macro. Instead, just set an
ISP_SMPLOCK define based on the previous 5.4 major/minor release
define of PVS- because this allows us to turn it off easier.

Catch up to moving headers:
- machine/ipl.h -> sys/ipl.h
- machine/mutex.h -> sys/mutex.h

compile time will build in mutex locks, otherwise the old locking (splcam/splx

We still depend on config_intr_hook to tell us when it's okay to call
msleep instead of polling. It'd be real nice if we could do this early
enough to not hang up a machine struggling with a bad Fibre Channel loop,
but that's still to come.

roll platform minor

Add in the now required malloc.h include. I guess somebody
was busy hackin' w/o checking kernel compiles.

roll platform versions to 5.0

Turn back on fast posting- the code that turns it off (for 1020/1040) is
now in isp.c

Approved: jkh@freebsd.org

There seems to be some problems, particularly on alpha, with
FAST POSTING enabled for parallel SCSI. Be sure about things
and disable it for now.

Role platform minor revision. Add in some target mode only
private structure definitions.

Add Dual LVD bus (1280) support
