Subject: [PATCH] MIPS: traps: Fix SIGFPE information leak from `do_ov' and
 `do_trap_or_bp'

commit e723e3f7f9591b79e8c56b3d7c5a204a9c571b55 upstream.

Avoid sending a partially initialised `siginfo_t' structure along SIGFPE
signals issued from `do_ov' and `do_trap_or_bp', leading to information
leaking from the kernel stack.
