From 314992b1a48a5a2a0f2b14195f959ad2c3f5b3ff Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Thu, 3 Jan 2013 14:17:18 +0100 Subject: linux-user: fix mips 32-on-64 prealloc case Bug-Debian: http://bugs.debian.org/668658 MIPS only supports 31 bits of virtual address space for user space, so let's make sure we stay within that limit with our preallocated memory block. This fixes the MIPS user space targets when executed without command line option.
