Just some misc bug fixes for 4.9.
* 'drm-next-4.9' of git://people.freedesktop.org/~agd5f/linux:
drm/amdgpu: revert "use more than 64KB fragment size if possible"
drm/amdgpu: warn if dp aux is still attached on free
drm/amdgpu/dce11: add missing drm_mode_config_cleanup call
drm/amdgpu: also track late init state
drm/amdgpu/virtual_dce: adjust config ifdef
drm/amdgpu/vce: add support for hw config packet (v2)
drm/amdgpu: clean up to set fw_offset as 0 twice
drm/amdgpu: remove DRM_AMD_POWERPLAY
drm/radeon: Prevent races on pre DCE4 between flip submission and completion.
drm/radeon: Slightly more robust flip completion handling for < DCE-4

*
+ * NOTE: Drivers using this to send out the event in struct &drm_crtc_state
+ * as part of an atomic commit must ensure that the next vblank happens at
+ * exactly the same time as the atomic commit is committed to the hardware. This
+ * function itself does **not** protect again the next vblank interrupt racing
+ * with either this function call or the atomic commit operation. A possible
+ * sequence could be:
+ *
+ * 1. Driver commits new hardware state into vblank-synchronized registers.
+ * 2. A vblank happens, committing the hardware state. Also the corresponding
+ * vblank interrupt is fired off and fully processed by the interrupt
+ * handler.
+ * 3. The atomic commit operation proceeds to call drm_crtc_arm_vblank_event().
+ * 4. The event is only send out for the next vblank, which is wrong.
+ *
+ * An equivalent race can happen when the driver calls
+ * drm_crtc_arm_vblank_event() before writing out the new hardware state.
+ *
+ * The only way to make this work safely is to prevent the vblank from firing
+ * (and the hardware from committing anything else) until the entire atomic
+ * commit sequence has run to completion. If the hardware does not have such a
+ * feature (e.g. using a "go" bit), then it is unsafe to use this functions.
+ * Instead drivers need to manually send out the event from their interrupt
+ * handler by calling drm_crtc_send_vblank_event() and make sure that there's no
+ * possible race with the hardware committing the atomic update.
+ *
* Caller must hold event lock. Caller must also hold a vblank reference for
* the event @e, which will be dropped when the next vblank arrives.

+ * - The event is for a CRTC which is being disabled through this
+ * atomic commit. In that case the event can be send out any time
+ * after the hardware has stopped scanning out the current
+ * framebuffers. It should contain the timestamp and counter for the
+ * last vblank before the display pipeline was shut off.
+ *
+ * - For a CRTC which is enabled at the end of the commit (even when it
+ * undergoes an full modeset) the vblank timestamp and counter must
+ * be for the vblank right before the first frame that scans out the
+ * new set of buffers. Again the event can only be sent out after the
+ * hardware has stopped scanning out the old buffers.
+ *
+ * - Events for disabled CRTCs are not allowed, and drivers can ignore
+ * that case.
+ *
+ * This can be handled by the drm_crtc_send_vblank_event() function,
+ * which the driver should call on the provided event upon completion of
+ * the atomic commit. Note that if the driver supports vblank signalling
+ * and timestamping the vblank counters and timestamps must agree with
+ * the ones returned from page flip events. With the current vblank
+ * helper infrastructure this can be achieved by holding a vblank
+ * reference while the page flip is pending, acquired through
+ * drm_crtc_vblank_get() and released with drm_crtc_vblank_put().
+ * Drivers are free to implement their own vblank counter and timestamp
+ * tracking though, e.g. if they have accurate timestamp registers in
+ * hardware.
+ *
+ * For hardware which supports some means to synchronize vblank
+ * interrupt delivery with committing display state there's also
+ * drm_crtc_arm_vblank_event(). See the documentation of that function
+ * for a detailed discussion of the constraints it needs to be used
