Pull up following revision(s) (requested by riastradh in ticket #1650):
sys/compat/sunos32/sunos32_misc.c: revision 1.86
sys/compat/ossaudio/ossaudio.c: revision 1.85
sys/compat/linux32/arch/amd64/linux32_machdep.c: revision 1.48
compat_sunos32: Memset zero before copyout.
Unclear if this can leak anything but let's be on the safe side.
compat_ossaudio: Zero-initialize idat before copyout.
Unclear if there are any paths to the copyout without initialization,
but let's play it safe to keep the auditing effort low.
linux32_rt_sendsig: Memset zero before copyout.
Not sure if there's any padding here, but it's a pretty big
structure, fairly likely, so let's be rather safe than sorry.
