lguest: send trap 13 through to userspace. We copy 7 bytes at eip for userspace's instruction decode; we have to carefully handle the case where eip is at the end of a page. We can't leave this to userspace since kernel has all the page table decode logic. The decode logic moves to userspace, basically unchanged. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
