Backport the aio poll fixes to 5.4.  This resolves conflicts in patches
1 and 4.  They are "trivial" conflicts, but I'm sending this to make
sure patches don't get dropped.

Eric Biggers (5):
  wait: add wake_up_pollfree()
  binder: use wake_up_pollfree()
  signalfd: use wake_up_pollfree()
  aio: keep poll requests on waitqueue until completed
  aio: fix use-after-free due to missing POLLFREE handling
