cde586a75c Fix a few nits relative to the previous changes:
- Don't leak the config lock if detach() fails due to the controller char
  dev being open.
- Close a race between detach() and a process opening the controller char
  dev.

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.

741367d5a5 Add in a bunch of things to the mfi driver:
- Linux ioctl support, with the other Linux changes MegaCli
	will run if you mount linprocfs & linsysfs then set
	sysctl compat.linux.osrelease=2.6.12 or similar.  This works
	on i386.  It should work on amd64 but not well tested yet.
	StoreLib may or may not work.  Remember to kldload mfi_linux.
      - Add in AEN (Async Event Notification) support so we can
	get messages from the firmware when something happens.
	Not all messages are in defined in event detail.  Use
	event_log to try to figure out what happened.
      - Try to implement something like SIGIO for StoreLib.  Since
	mrmonitor doesn't work right I can't fully test it.  StoreLib
	works best with the rh9 base.  In theory mrmonitor isn't
	needed due to native driver support of AEN :-)
Now we can configure and monitor the RAID better.

2e21a3ef7e Add a driver for the new LSI MegaRAID SAS controller family. The 'MFI' name
is derived from the phrase 'MegaRAID Firmware Interface' used by LSI.  This

management device.  It is MPSAFE, INTR_FAST, and 64-bit capable.
