Just sent a patch

I need a little help from Masami Hiramatsu to understand what the plan is here:
Do we just need to remove those files now that jprobes are gone, or do
we actually
want to restore the functionality using some other replacement code?

I'm asking because the __deprecated warning seems unhelpful if there
isn't an easy
way to address the warning.

Mostly unrelated issues all have existing patches.

Sent a patch for these too

This came through arm-soc, I also have a patch for it, which should go through
netdev, though that leaves arm-soc showing that warning.
