fa1e6ef4ef - Fix from jhb for failing I/O request when bus_dmamap_load fails.
- Fix to ioctl path in which the length could be 0 which means
  no data in/out from LSI.
- Fix to ioctl path in which the data in the sense data space
  of the ioctl packet is a really a pointer to some location in
  user-space.  From LSI re-worked a bit by me.
- Add HW support for next gen cards from LSI.

Thanks to LSI for their support!

2137b017d7 Tweak the output of event log messages from the controller:
- Each log entry contains a text description in the "description" field of
  the entry.  The existing decode logic always ended up duplicating
  information that was already in the description string.  This made the
  logs overly verbose.  Now we just print out the description string.
- Add some simple parsing of the timestamp and event classes.

c1ed06a84b Adjust the handling of pending log events during boot:
- Fetch events from the controller in batches of 15 rather than a single
  event at a time.
- When fetching events from the controller, honor the event class and
  locale settings (via hw.mfi tunables).  This also allows the firmware to
  skip over unwanted log entries resulting in fewer requests to the
  controller if there many unwanted log entries since the last clean
  shutdown.
- Don't drop the driver mutex while decoding an event.
- If we get an error other than MFI_STAT_NOT_FOUND (basically EOF for
  hitting the end of the event log) then emit a warning and bail on
  processing further log entries.

b50569b71d Prepare for future integration between CAM and newbus. xpt_bus_register
now takes a device_t to be the parent of the bus that is being created.
Most SIMs have been updated with a reasonable argument, but a few exceptions
just pass NULL for now.  This argument isn't used yet and the newbus
integration likely won't be ready until after 7.0-RELEASE.

5be25877a1 Add in a couple of things:
-	In the ioctl path let command get queued up and return
	when complete _without_ blocking the driving waiting for
	the response.  This way the driver doesn't "lock up" for
	~30s during a flash command.  Submitted by scottl.
      -	Add a guard so that if a DCMD of 0 is sent down the ioctl
	path don't send it to the controller.  Return with a
	status of OK.  This is a little strange since MegaCli
	doesn't seem to like something and will issue some DCMD
	of 0.  This doesn't happen under Linux.  So the emulation
	needs to be improved but I'm not sure what.  Another strange
	thing is that when a DCMD of 0 gets issued under i386 the
	controller returns OK but in amd64 the context is messed
	up.
      -	Add a guard so the context has to be with-in the legal
	limit so we get a reasonable error assertion versus random
	panic.

It's going to be a challenge to figure out why MegaCli is not totally
happy and then sends some bogus commands.  This means that flashing
firmware via the Linux tool won't work since it generates a DCMD of
0 when it should be opening the firmware for a flash update.  Without
this problem flashing works fine.  This means there is no publicly
available tool to upgrade the RAID firmware under FreeBSD right now.

I plan to MFC all of the mfi changes to 6.X shortly.  This might not
include the SCSI pass-through changes.

812819c7b1 Some relatively minor changes and bug fixes:
1)	s/mi/mfi/ in FreeBSD ioctl path
     2)	add in "\n" on various failure messages
     3)	cap the length of time to abort an AEN command
     4)	fix passing sense data back to user to make Dell's Linux firmware
	upgrade tool happy.
     5)	bump the MFI_POLL_TIMEOUT_SECS from 10s to 50s since the
	firmware flash command can take ~40s to return.

This is some clean-up and enables RAID firmware to updated via Dell's
tool.  Note Dell's tool requires the updates to the Linux emulator
that has been done in -current with TLS etc.

I need to discuss with scottl how to better submit mfi commands to
the firmware via the ioctl path so we don't do it in polled mode.

3c77cee1ba Change the internal API for polled commands. Calling mfi_polled_command
after calling mfi_mapcmd is no longer needed, so long as the MFI_CMD_POLLED
flag is set.  This change eliminates the possibility of a polled command
getting posted twice to the driver.  This is turn fixes panics on shutdown
when INVARIANTS is set.

c2be47f25f - Add in FreeBSD native ioctl that models the Linux version.
- Add a translation so the Linux ioctl's don't conflict with
  the FreeBSD definition.
- Assume Linux 32bit emulation on amd64.
This was tested on i386 and amd64 with the 32bit Linux MegaCli.
Eventually we should do a 32bit native FreeBSD translation app.
