fs/file.c one is a genuine missing speculation barrier in pick_file() (reachable
e.g. via close(2)); alpha one is strictly speaking not a bug fix, but only
because confusion between preempt_enable() and preempt_disable() is harmless
on architecture without CONFIG_PREEMPT. Looks like alpha.git picked the
wrong version of patch - that braino used to be there in early versions, but
it had been fixed quite a while ago... I've checked what ended up in mainline,
fortunately all other parts of commit match the latest variant in my tree.
