blu_plug: Do not offline a cpu if it's boosted by cpu-boost
Revert "bluactive: let's try and live without the idle notifier and rely on the timer instead."

This reverts commit 5905f0a010bfd2b23d31d82e1923c262e6a511c6.
net/l2tp: don't fall back on UDP [get|set]sockopt

The l2tp [get|set]sockopt() code has fallen back to the UDP functions
for socket option levels != SOL_PPPOL2TP since day one, but that has
never actually worked, since the l2tp socket isn't an inet socket.

As David Miller points out:

  "If we wanted this to work, it'd have to look up the tunnel and then
   use tunnel->sk, but I wonder how useful that would be"

Since this can never have worked so nobody could possibly have depended
on that functionality, just remove the broken code and return -EINVAL.
