Module Name: src
Committed By: tsutsui
Date: Sat Jul 26 13:24:34 UTC 2014
Modified Files:
src/sys/arch/atari/include: vmparam.h
Log Message:
Reorganize and bump VM related constants.
- sync VM_MAXUSER_ADDRESS and VM_MAX_ADDRESS with other hp300 derived ports
and use same definitions for USRSTACK as other m68k ports
(no worth to have sun3/sunos compat in these days)
- remove unused KUSER_AREA
- bump MAXTSIZ, MAXDSIZ, and MAXSSIZ
These changes allow my 64MB TT030 build pkgsrc/textproc/icu
which seems to require >200MB VA space.
(note our current 040/060 pmap implementation can't handle >224MB VA size)
