As this is a pre-condition for the set_fs removal I'd really like to
get the actual changes in.  All these conflicts seem to be about the
last three cleanup patches just doing renaming, so can we just skip
those three for now?  Then we can do the rename right after 5.8-rc1
when we have the least chances for conflicts.
