The first fixes ddd535f1ea3eb27e, which appeared in v4.14-rc1.  The
second fixes 5d2917d469faab72, which appeared in v4.5-rc1.

After the merge window I normally just pull in critical fixes and
fixes to things we merged during the window.

I think the first makes sense for v4.15 because it can cause a crash
with no obvious way to debug it.  The second one feels like v4.16
material to me.

Thoughts?  We're trying to sort out how to handle this sort of thing
between Lorenzo and myself, so I apologize for the confusion here.
