      FS-Cache: Initialise stores_lock in netfs cookie · fa5eeba8
      David Howells authored
      Initialise the stores_lock in fscache netfs cookies.  Technically, it
      shouldn't be necessary, since the netfs cookie is an index and stores no
      data, but initialising it anyway adds insignificant overhead.

       "This is the main request for rc6, since really the one earlier was the
        rc5 one :-)
      
        The main thing are the nouveau specific race fixes for the connector
        locking bug we fixed in -next and reverted here as it has quite large
        prereqs. These two fixes should solve the problem at that level and we
        can fix it properly in 4.11
      
        Otherwise i915 has a bunch of changes, one ABI change for GVT related
        stuff, some VC4 leak fixes, one core fence fix and some AMD changes,
        oh and one ast hang avoidance fix.
      
        Hoping it calms down around now"

      More fixes than I'd like at this stage, but I think the holidays and
      conferences have delayed finding and fixing the stuff a bit. Almost all
      of them have Fixes: tags, so it's not just random fixes, we can point
      fingers at the commits that broke stuff.
      
      There's an ABI fix to GVT from Alex, before we go on an release a kernel
      with the wrong attribute name.

      drm/nouveau: Handle fbcon suspend/resume in seperate worker · 15266ae3
      Lyude Paul authored
      Resuming from RPM can happen while already holding
      dev->mode_config.mutex. This means we can't actually handle fbcon in
      any RPM resume workers, since restoring fbcon requires grabbing
      dev->mode_config.mutex again. So move the fbcon suspend/resume code into
      it's own worker, and rely on that instead to avoid deadlocking.
      
      This fixes more deadlocks for runtime suspending the GPU on the ThinkPad
      W541. Reproduction recipe:
      
       - Get a machine with both optimus and a nvidia card with connectors
         attached to it
       - Wait for the nvidia GPU to suspend
       - Attempt to manually reprobe any of the connectors on the nvidia GPU
         using sysfs
       - *deadlock*

      drm/nouveau: Don't enabling polling twice on runtime resume · cae9ff03
      Lyude Paul authored
      As it turns out, on cards that actually have CRTCs on them we're already
      calling drm_kms_helper_poll_enable(drm_dev) from
      nouveau_display_resume() before we call it in
      nouveau_pmops_runtime_resume(). This leads us to accidentally trying to
      enable polling twice, which results in a potential deadlock between the
      RPM locks and drm_dev->mode_config.mutex if we end up trying to enable
      polling the second time while output_poll_execute is running and holding
      the mode_config lock. As such, make sure we only enable polling in
      nouveau_pmops_runtime_resume() if we need to.
      
      This fixes hangs observed on the ThinkPad W541

      The original ast driver will access some BMC configuration through P2A bridge
      that can be disabled since AST2300 and after.
      It will cause system hanged if P2A bridge is disabled.
