scottl 9126bcda9d Massive overhaul of MPT Fusion driver: 
o Add timeout error recovery (from a thread context to avoid
  the deferral of other critical interrupts).
o Properly recover commands across controller reset events.
o Update the driver to handle events and status codes that
  have been added to the MPI spec since the driver was
  originally written.
o Make the driver more modular to improve maintainability and
  support dynamic "personality" registration (e.g. SCSI Initiator,
  RAID, SAS, FC, etc).
o Shorten and simplify the common I/O path to improve driver
  performance.
o Add RAID volume and RAID member state/settings reporting.
o Add periodic volume resynchronization status reporting.
o Add support for sysctl tunable resync rate, member write cache
  enable, and volume transaction queue depth.

Detailed Changes
================
mpt.c mpt_cam.c mpt_raid.c mpt_pci.c:
o Add support for personality modules.  Each module exports
  load, and unload module scope methods as well as probe, attach,
  event, reset, shutdown, and detach  per-device instance
  methods

mpt.c mpt.h mpt_pci.c:
o The driver now associates a callback function (via an
  index) with every transaction submitted to the controller.
  This allows the main interrupt handler to absolve itself
  of any knowledge of individual transaction/response types
  by simply calling the callback function "registered" for
  the transaction.  We use a callback index instead of a
  callback function pointer in each requests so we can
  properly handle responses (e.g. event notifications)
  that are not associated with a transaction.  Personality
  modules dynamically register their callbacks with the
  driver core to receive the callback index to use for their
  handlers.

o Move the interrupt handler into mpt.c.  The ISR algorithm
  is bus transport and OS independent and thus had no reason
  to be in mpt_pci.c.

o Simplify configuration message reply handling by copying
  reply frame data for the requester and storing completion
  status in the original request structure.

o Add the mpt_complete_request_chain() helper method and use
  it to implement reset handlers that must abort transactions.

o Keep track of all pending requests on the new
  requests_pending_list in the softc.

o Add default handlers to mpt.c to handle generic event
  notifications and controller reset activities.  The event
  handler code is largely the same as in the original driver.
  The reset handler is new and terminates any pending transactions
  with a status code indicating the controller needs to be
  re-initialized.

o Add some endian support to the driver.  A complete audit is
  still required for this driver to have any hope of operating
  in a big-endian environment.

o Use inttypes.h and __inline.  Come closer to being style(9)
  compliant.

o Remove extraneous use of typedefs.

o Convert request state from a strict enumeration to a series
  of flags.  This allows us to, for example, tag transactions
  that have timed-out while retaining the state that the
  transaction is still in-flight on the controller.

o Add mpt_wait_req() which allows a caller to poll or sleep
  for the completion of a request.  Use this to simplify
  and factor code out from many initialization routines.
  We also use this to sleep for task management request
  completions in our CAM timeout handler.

mpt.c:
o Correct a bug in the event handler where request structures were
  freed even if the request reply was marked as a continuation
  reply. Continuation replies indicate that the controller still owns
  the request and freeing these replies prematurely corrupted
  controller state.

o Implement firmware upload and download. On controllers that do
  not have dedicated NVRAM (as in the Sun v20/v40z), the firmware
  image is downloaded to the controller by the system BIOS. This
  image occupies precious controller RAM space until the host driver
  fetches the image, reducing the number of concurrent I/Os the
  controller can processes. The uploaded image is used to
  re-program the controller during hard reset events since the
  controller cannot fetch the firmware on its own. Implementing this
  feature allows much higher queue depths when RAID volumes
  are configured.

o Changed configuration page accessors to allow threads to sleep
  rather than busy wait for completion.

o Removed hard coded data transfer sizes from configuration page
  routines so that RAID configuration page processing is possible.

mpt_reg.h:
o Move controller register definitions into a separate file.

mpt.h:
o Re-arrange includes to allow inlined functions to be
  defined in mpt.h.

o Add reply, event, and reset handler definitions.

o Add softc fields for handling timeout and controller
  reset recovery.

mpt_cam.c:
o Move mpt_freebsd.c to mpt_cam.c.  Move all core functionality,
  such as event handling, into mpt.c leaving only CAM SCSI
  support here.

o Revamp completion handler to provide correct CAM status for
  all currently defined SCSI MPI message result codes.

o Register event and reset handlers with the MPT core.  Modify
  the event handler to notify CAM of bus reset events.  The
  controller reset handler will abort any transactions that
  have timed out.  All other pending CAM transactions are
  correctly aborted by the core driver's reset handler.

o Allocate a single request up front to perform task management
  operations.  This guarantees that we can always perform a
  TMF operation even when the controller is saturated with other
  operations.  The single request also serves as a perfect
  mechanism of guaranteeing that only a single TMF is in flight
  at a time - something that is required according to the MPT
  Fusion documentation.

o Add a helper function for issuing task management requests
  to the controller.  This is used to abort individual requests
  or perform a bus reset.

o Modify the CAM XPT_BUS_RESET ccb handler to wait for and
  properly handle the status of the bus reset task management
  frame used to reset the bus.  The previous code assumed that
  the reset request would always succeed.

o Add timeout recovery support.  When a timeout occurs, the
  timed-out request is added to a queue to be processed by
  our recovery thread and the thread is woken up.  The recovery
  thread processes timed-out command serially, attempting first
  to abort them and then falling back to a bus reset if an
  abort fails.

o Add calls to mpt_reset() to reset the controller if any
  handshake command, bus reset attempt or abort attempt
  fails due to a timeout.

o Export a secondary "bus" to CAM that exposes all volume drive
  members as pass-thru devices, allowing CAM to perform proper
  speed negotiation to hidden devices.

o Add a CAM async event handler tracking the AC_FOUND_DEVICE event.
  Use this to trigger calls to set the per-volume queue depth once
  the volume is fully registered with CAM. This is required to avoid
  hitting firmware limits on volume queue depth.  Exceeding the
  limit causes the firmware to hang.

mpt_cam.h:
o Add several helper functions for interfacing to CAM and
  performing timeout recovery.

mpt_pci.c:
o Disable interrupts on the controller before registering and
  enabling interrupt delivery to the OS.  Otherwise we risk
  receiving interrupts before the driver is ready to receive
  them.

o Make use of compatibility macros that allow the driver to
  be compiled under 4.x and 5.x.

mpt_raid.c:
o Add a per-controller instance RAID thread to perform settings
   changes and query status (minimizes CPU busy wait loops).

o Use a shutdown handler to disable "Member Write Cache Enable"
  (MWCE) setting for RAID arrays set to enable MWCE During Rebuild.

o Change reply handler function signature to allow handlers to defer
  the deletion of reply frames. Use this to allow the event reply
  handler to queue up events that need to be acked if no resources
  are available to immediately ack an event. Queued events are
  processed in mpt_free_request() where resources are freed. This
  avoids a panic on resource shortage.

o Parse and print out RAID controller capabilities during driver probe.

o Define, allocate, and maintain RAID data structures for volumes,
  hidden member physical disks and spare disks.

o Add dynamic sysctls for per-instance setting of the log level, array
  resync rate, array member cache enable, and volume queue depth.

mpt_debug.c:
o Add mpt_lprt and mpt_lprtc for printing diagnostics conditioned on
  a particular log level to aid in tracking down driver issues.

o Add mpt_decode_value() which parses the bits in an integer
  value based on a parsing table (mask, value, name string, tuples).

mpilib/*:
o Update mpi library header files to latest distribution from LSI.
