I think this one needs to be dropped, as I commented on a similar patch for
another architecture (I forget which one). We really should implemente all
the syscalls below, with the possible exception of the pkey calls.

Note that we even list pkey_* in architectures that don't support the feature.
See also the commit text for a60f7b69d92c ("generic syscalls: Wire up
memory protection keys syscalls")
