Roll minor revision- for once we'll use this because.... if revision >= 5.4, compile time will build in mutex locks, otherwise the old locking (splcam/splx with a recursion counter) will be compiled in. 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 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. 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. Contributors: jake, jhb, jasone (in no particular order)

We still depend on config_intr_hook to tell us when it's okay to call msleep instead of polling.

A wad of changes- prepping for 1080/1240 support (which caused a massive thwank in register layout goop). A different mboxcmd approach. Some PDB change infrastructure. Some better management of loopdown/loopup events (keep them distinct from resource starvation for simq freeze/unfreeze actions).

Core version 2.0 cleanup/rewrite. Things get rearranged and changed quite a bit so that all of the ports have a similar set of required macros/definitions (and in similar places in the isp_<platform>.h file). Some new macros/functions added- Mailbox Acquire/Relase macros, NANOTIME macros, SNPRINTf and STRNCAT. MemoryBarrier beomes MEMORYBARRIER with much stronger types.

Add in isp_lock/isp_unlock inlines. Add in an islocked/intsok flag to isp_osinfo substructure (all in prep for SMP). Define MBOX_WAIT_COMPLETE and MBOX_NOTIFY_COMPLETE macros so that we can now (temp) use tsleep to wait for mailbox completion. Requires us to guess whether we're servicing an interrupt or not- will use intr_nesting_level. Add local strncat function.

Roll platform major && minor (major now tracks FreeBSD major release). Add in null SWIZZLE definitions. Add in CFGPRINTF define. Change default debug level to refer to an external isp_debug variable. Remove inline functions as they're now in isp_inline.h and include that file.
