Subject: [PATCH 0/3] Use jump_label for sched_feat()

These patches implement sched_feat() using jump_labels. The first is a section
mismatch fix. The second patch provides a little infrastructure and the third
patch applies it to make sched_feat() use static_branch().

It uses static_branch() coupled with unlikely/likely in order to control the
branch block position. I haven't checked if it works, but it likely doesn't,
although it should.
