Doug Ambrisko a6ba0fd64d MFhead_mfi r227068
First cut of new HW support from LSI and merge into FreeBSD.
	Supports Drake Skinny and ThunderBolt cards.
MFhead_mfi r227574
	Style
MFhead_mfi r227579
	Use bus_addr_t instead of uintXX_t.
MFhead_mfi r227580
	MSI support
MFhead_mfi r227612
	More bus_addr_t and remove "#ifdef __amd64__".
MFhead_mfi r227905
	Improved timeout support from Scott.
MFhead_mfi r228108
	Make file.
MFhead_mfi r228208
	Fixed botched merge of Skinny support and enhanced handling
	in call back routine.
MFhead_mfi r228279
	Remove superfluous !TAILQ_EMPTY() checks before TAILQ_FOREACH().
MFhead_mfi r228310
	Move mfi_decode_evt() to taskqueue.
MFhead_mfi r228320
	Implement MFI_DEBUG for 64bit S/G lists.
MFhead_mfi r231988
	Restore structure layout by reverting the array header to
	use [0] instead of [1].
MFhead_mfi r232412
	Put wildcard pattern later in the match table.
MFhead_mfi r232413
	Use lower case for hexadecimal numbers to match surrounding
	style.
MFhead_mfi r232414
	Add more Thunderbolt variants.
MFhead_mfi r232888
	Don't act on events prior to boot or when shutting down.
	Add hw.mfi.detect_jbod_change to enable or disable acting
	on JBOD type of disks being added on insert and removed on
	removing.  Switch hw.mfi.msi to 1 by default since it works
	better on newer cards.
MFhead_mfi r233016
	Release driver lock before taking Giant when deleting children.
	Use TAILQ_FOREACH_SAFE when items can be deleted.  Make code a
	little simplier to follow.  Fix a couple more style issues.
MFhead_mfi r233620
	Update mfi_spare/mfi_array with the actual number of elements
	for array_ref and pd.  Change these max. #define names to avoid
	name space collisions.  This will require an update to mfiutil
	It avoids mfiutil having to do a magic calculation.

	Add a note and #define to state that a "SYSTEM" disk is really
	what the firmware calls a "JBOD" drive.

Thanks to the many that helped, LSI for the initial code drop,
mav, delphij, jhb, sbruno that all helped with code and testing.
