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. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>
