According to comments in /usr/include/linux/eventpoll.h, x86_64 have
the same memory layout of struct target_epoll_event as i386. So on a
aligned host, if x86_64 should be packed, i386 will also need.
This has been tested with a i386 guest on an arm host: without the
patch, wineserver crashes (core).
