From ddaa7e5a2ad0ef20fd3d1cc44a9ade75e5eabcfc Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Sat, 6 Jul 2013 14:17:53 +0200 Subject: linux-user: Fix epoll on ARM hosts The epoll emulation uses data structures without packing them, so the compiler might choose to add padding inside. This patch makes the most offending one (target_epoll_event) a packed structure to make sure we don't pad it by accident. ARM would pad it, so declare the padding mandatory for ARM targets. This fixes i386-on-ARM epoll emulation for me.
