From 99d1672b3def2c3d6db003bd02d138ac0e07ca53 Mon Sep 17 00:00:00 2001 From: peter Date: Fri, 23 May 2003 05:07:33 +0000 Subject: Deal with the user VM space expanding. 32 bit applications do not like having their stack at the 512GB mark. Give 4GB of user VM space for 32 bit apps. Note that this is significantly more than on i386 which gives only about 2.9GB of user VM to a process (1GB for kernel, plus page table pages which eat user VM space).
