       "Mostly radeon, more fixes for dynamic power management which is is off
        by default for this release anyways, but there are a large number of
        testers, so I'd like to keep merging the fixes.
      
        Otherwise, radeon UVD fixes affecting suspend/resume regressions, i915
        regression fixes, one for your mac mini, ast, mgag200, cirrus ttm fix
        and one regression fix in the core"

      dlm: kill the unnecessary and wrong device_close()->recalc_sigpending() · 201d3dfa
      Oleg Nesterov authored
      device_close()->recalc_sigpending() is not needed, sigprocmask() takes
      care of TIF_SIGPENDING correctly.
      
      And without ->siglock it is racy and wrong, it can wrongly clear
      TIF_SIGPENDING and miss a signal.
      
      But even with this patch device_close() is still buggy:
      
        1. sigprocmask() should not be used, we have set_task_blocked(),
           but this is minor.
      
        2. We should never block SIGKILL or SIGSTOP, and this is what
           the code tries to do.
      
        3. This can't protect against SIGKILL or SIGSTOP anyway. Another
           thread can do signal_wake_up(), say, do_signal_stop() or
           complete_signal() or debugger.
      
        4. sigprocmask(SIG_BLOCK, allsigs) doesn't necessarily clears
           TIF_SIGPENDING, say, freezing() or ->jobctl.
      
        5. device_write() looks equally wrong by the same reason.
      
      Looks like, this tries to protect some wait_event_interruptible() logic
      from signals, it should be turned into uninterruptible wait.  Or we need
      to implement something like signals_stop/start for such a use-case.
