Subject: Do not define vax-inspired LOWPAGES and HIGHPAGES anymore, they make no
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=35019321050739e9b261a08543d79a5d336b4785;p=openbsd

Do not define vax-inspired LOWPAGES and HIGHPAGES anymore, they make no
sense on m68k. Give USRSTACK its real (HP-UX compatible) value instead of
computing it from HIGHPAGES.

No functional change.
