		HPSA specific ioctls
		====================

		For compatibility with applications written for the cciss driver, many, but

		include/linux/cciss_ioctl.h

		CCISS_REGNEWDISK
		CCISS_REGNEWD

		CCISS_DEREGDISK, CCISS_REGNEWDISK, CCISS_REGNEWD
		The above three ioctls all do exactly the same thing, which is to cause the driver
		to rescan for new devices. This does exactly the same thing as writing to the
		hpsa specific host "rescan" attribute.

		CCISS_GETPCIINFO

		Returns PCI domain, bus, device and function and "board ID" (PCI subsystem ID).

		CCISS_GETDRIVVER
		Returns driver version in three bytes encoded as::
