b65c047639 adv_pci.c:
Update list of supported products.
	Adjust probe message to include the ASC3030.

advansys.c:
	Fix a long standing bug in the error recovery strategy.  In order
	to keep recovery simple, we freeze the SIMQ, stopping the XPT from
	submitting new requests.  Unfortunately, we also will freeze the
	SIMQ if bus_dmamap_load blocks or we run out of controller resources.
	On cards with limited resources it was possible to freeze the
	SIM a second time and never unfreeze it.  Now we more carefully
	track our exception state so we never freeze the SIMQ more than
	once.

	Don't rely on pointers fitting in a 32bit field stored in the
	per-transaction data structures on the card.  Use an index to
	an array of transaction mapping structures instead.  This should
	allow this driver to work on the Alpha.

	Deal with the ASC3030 which is almost idistinguishable from the
	ASC3050.  Unfortunately the ASC3030 does not work at Ultra speeds,
	so if we can't find an eeprom, we must assume that ultra is disabled.
	The SIIG cards using the 3030 do not have eeproms.  As a side effect,
	we now honor the ultra disable bit in the eeprom if it is present.

	Don't bother attempting to write corrected eeprom data back to the
	eeprom.  We can function just fine if the data is corrupted and
	I'd rather not risk messing up the user's eeprom.

	Modify the interrupt handler to catch latched external bus rests.

	Dynamically determine the maximum number of S/G elements we can
	map at a single time.  The nature of the firmware interface for
	these cards makes this value dependent on the number of "queues"
	the card can support.

c1664fa91a Properly set the alignment argument to bus_dma_tag_create(). If we
don't care about the alignment, set it to 1, meaning single byte alignment.

41b420910c Simplify the COMPAT_PCI_DRIVER/DATA_SET hack. We can add:
#define COMPAT_PCI_DRIVER(name,data) DATA_SET(pcidevice_set,data)
.. to 2.2.x and 3.x if people think it's worth it.  Driver writers can do
this if it's not defined.  (The reason for this is that I'm trying to
progressively eliminate use of linker_sets where it hurts modularity and
runtime load capability, and these DATA_SET's keep getting in the way.)

d6f4bd18f5 Use COMPAT_PCI_DRIVER() for registration if it exists. This shouldn't
hurt the driver portability to 3.x too much for where drivers are shared.

b6ee7c1b3f Staticize the overrun buffer so that they are not shared between
cards of different bus types as each bus type may have a different
bus mapping.
