OK, well, on ports that have a constant NBPG and therefore can sanely
define UPAGES, UPAGES * NBPG = USPACE. The intent on the sparc is
that you've got a variable page size, so you've got a variable number
of UPAGES.
That identity should tell you all you need to know to fix the code.
(UPAGES = USPACE / NBPG, but note that the latter's not a constant on
the sparc and you've therefore gotta get it from the kernel. 8-)
