This is only a boring prerequisite that doesn't add any security ...
Jim Mattson gave r-b to [v1 3/3] and was a significant contributor to
the patches, David Hildenbrandt reviewed [v2 2,3/3] and there have been
only minor changes since.

v3 looks good to me, so I'll pull if there are no more requirements from
pti.
