most of these inlines had been bloated in -current far beyond their
original intent. Normalize prototypes and function declarations to be ANSI
only (half already were). And do some general cleanup.
(kernel size also reduced by 50-100K, but that isn't the prime intent)
For fibre channel, start going for the gusto and using AC_FOUND_DEVICE
and AC_LOST_DEVICE calls to xpt_async when devices appear and disappear
as the loop or fabric changes.
ISPASYNC_FW_CRASH is the async event code where the platform layer
deals with a firmware crash.
some of the RIO (reduced interrupt operation) stuff. Add 64 bit
data list (DSD type 1) and arbitrary data list (DSD type 2)
data structure defines.
Add macros that parameterize usage of the Request/Response in/out
queue pointers. When we finish 2300 support, different registers
will be accessed for the 2300.
part of the PCI block for the 2300- not software convention usage
of the mailbox registers- so we macrosize in/out pointer usage.
Only report that a LIP destroyed commands if it actually destroyed
commands. Get the chan/tgt/lun order correct. Fix a longstanding
stupid bug that caused us to try and issue a command with a tag on
Channel B because we were checking the tagged capability for the
target against Channel A.
A firmware crash is now vectored out to platform specific code
as an async event.
Some minor formatting tweaks.
(this commit is just the first stage). Also add various GIANT_ macros to
formalize the removal of Giant, making it easy to test in a more piecemeal
fashion. These macros will allow us to test fine-grained locks to a degree
before removing Giant, and also after, and to remove Giant in a piecemeal
fashion via sysctl's on those subsystems which the authors believe can
operate without Giant.
- Move the lance_probe function to if_lnc.c.
- Support C-NET(98)S again.

These take an additional mutex argument, which is dropped before any
processes are made runnable. This can avoid contention on the mutex
if the processes would immediately acquire it, and is done in such a
way that wakeups will not be lost.

We already did this in the SMP case, and it is now maintained in the UP
case as well, and makes the code slightly more readable. Note that
curproc is always executing, thus the p != curproc test does not need to
be performed if the p_oncpu check is made.
We don't actually need to force a context switch of the current process.
The act of firing the event triggers a context switch to softclock() and
then switching back out again which is equivalent to a preemption, thus
no further work is needed on the local CPU.
1. Add SA_IO_TIMEOUT as an option (4 minutes default) to cover reads,
writes, wfm, test unit ready.
2. Add internal SCSIOP_TIMEOUT (e.g., for mode sense) at 1 minute. This
should not require an option, but is cleaner to parameterize.
