1d96f7e031 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.

f41b8dc90c - 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.

af202f9ad6 Allow hw.mfi.event_locale/hw.mfi.event_class to be set via loader. 
If an event doesn't match the criteria then don't print it.  Some
events are not saved in the log (<0 class events).

2b1d36a00f Change the event log dump on initial boot to use get_event versus 
AEN.  This makes the boot messages cleaner.  I now know how this
structure works so I can implement it versus guessing.  Remove the
not ready type code since it is ready now.

I added the time stamp/locale/class so people can parse messages better.
Create a sysctl so that we can set the locale/class level.

97363ee503 Change mfi_add_ld to "immediate command" mode since we need to enumerate 
potential boot disks during the probe so they are read for mount root.

Also release the command in mfi_shutdown.

2946fa1ebc Instead of using scsi probes to do device discovery, use the firmware 
commands to grab the device listing.  This resolves issues using
multiple volumes, where each volume was actually internally pointing
to target 0.

033f8e47d2 Fix missing \n and when there are no arg's that means just print out 
the description so we don't have to do any more queries.  Disable the
event query code until it figured out since but it is similar to the
AEN detail so we should be able to get that working.

2f056812a1 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.

cb08e1b408 Fix 64-bit DMA. The problem was an incorrect flag check. Thanks to Paul 
Saab for helping to track this down.  Fix a error with 32bit DMA size
calculation that seemed to be harmless.  Add a few micro-optimizations while
I'm here.

fe1496da44 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
driver provides a block interface to logical disks on the card and a minimal
management device.  It is MPSAFE, INTR_FAST, and 64-bit capable.

Thanks to Dell for providing hardware to test with and IronPort for
sponsoring the work.
