Because we need the 64-bit type, how about:

/* Offset of -0x00100000 with 64-bit bus addresses */
#define	PFOUR_COLOR_OFF_CMAP ((paddr_t) 0xfffffffffff00000)

(I think I have the correct number of f and 0)?

Alternatively we could define a new:

#define PFOUR_COLOR_OFF_CMAP64

and use that in sys/arch/sparc/dev/cgfour.c, so that sys/dev/sun/pfourreg.h
works for both sun3 and sparc (I have a slight preference for this).

Julian
