[PATCH 4.4,4.9 0/3] POLLFREE fix for 4.4 and 4.9

[Eric Biggers]

Please apply to 4.4 and 4.9.

These kernel versions don't have aio poll, but the fix for POLLFREE with
exclusive waiters is still applicable to them.  This series resolves
conflicts in all three patches, mostly due to POLLHUP and
wait_queue_head_t having been renamed in more recent kernels.

Eric Biggers (3):
  wait: add wake_up_pollfree()
  binder: use wake_up_pollfree()
  signalfd: use wake_up_pollfree()
