From d1f413ff30bb854d34e2bf3be2bcbe01170a9814 Mon Sep 17 00:00:00 2001 From: Joshua Lock Date: Fri, 16 Apr 2010 16:41:33 +0100 Subject: [PATCH] sanity.bbclass: handle lack of permission to read /proc/sys/vm/mmap_min_addr Patch from OE.dev by Martin Jansa to workaround that we on modern Linux we can no longer read this file. We need a better fix but best option will be to update to a newer, relocatable, QEMU release.
