From bf91a8cbb745b8c0ea2d184b0fe1123131c593ab Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Mon, 23 Jul 2012 10:24:14 +0200 Subject: [PATCH] linux-user: Fake /proc/cpuinfo MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fedora 17 for ARM reads /proc/cpuinfo and fails if it doesn't contain ARM related contents. This patch implements a quick hack to expose real /proc/cpuinfo data taken from a real world machine. The real fix would be to generate at least the flags automatically based on the selected CPU. Please do not submit this patch upstream until this has happened.
