58 * EV6 has a new superpage which can pass through 44 address bits.  (Umm, a
59 * superduperpage?) But, the firmware doesn't turn it on, so we use the old
60 * one and let the HW sign extend va/pa<40> to get us the pa<43> that makes
61 * the needed I/O space access. This is just as well; it means we don't have
62 * to worry about which GENERIC code might get called on other CPU models.
63 *
64 *	E.g., we want this:	      0x0801##a000##0000
65 *	We use this:		      0x0101##a000##0000
