2016-02-20ASoC: samsung: Use IRQ safe spin lock callsCharles Keepax
Lockdep warns of a potential lock inversion, i2s->lock is held numerous times whilst we are under the substream lock (snd_pcm_stream_lock). If we use the IRQ unsafe spin lock calls, you can also end up locking snd_pcm_stream_lock whilst under i2s->lock (if an IRQ happens whilst we are holding i2s->lock). This could result in deadlock.

2016-02-19arm64: mm: allow the kernel to handle alignment faults on user accessesEunTaik Lee
Although we don't expect to take alignment faults on access to normal memory, misbehaving (i.e. buggy) user code can pass MMIO pointers into system calls, leading to things like get_user accessing device memory. Rather than OOPS the kernel, allow any exception fixups to run and return something like -EFAULT back to userspace. This makes the behaviour more consistent with userspace, even though applications with access to device mappings can easily cause other issues if they try hard enough.

2016-02-19[media] v4l: vsp1: Add display list supportTakashi Saito
Display lists contain lists of registers and associated values to be applied atomically by the hardware. They lower the pressure on interrupt processing delays when reprogramming the device as settings can be prepared well in advance and queued to the hardware without waiting for the end of the current frame. Display list support is currently limited to the DRM pipeline.

2016-02-19[media] v4l: vsp1: Set the alpha value manually in RPF and WPF s_stream handlersLaurent Pinchart
The RPF and WPF alpha values are set through V4L2 controls and applied when starting the video stream by a call to v4l2_ctrl_handler_setup(). As that function uses the control handler mutex it can't be called in interrupt context, where the VSP+DU pipeline handler might need to reconfigure the pipeline. Set the alpha value manually in the RPF and WPF s_stream handler to ensure that the hardware is properly configured even when controlled without the userspace API. If the userspace API is enabled protect that with the control lock to avoid race conditions with userspace.

2016-02-19[media] v4l: vsp1: Make pipeline inputs array index by RPF indexLaurent Pinchart
The pipeline inputs array stores pointers to all RPFs contained in the pipeline. It's currently indexed contiguously by adding RPFs in the order they are found during graph walk. This can't easily support dynamic addition and removal of RPFs while streaming, which will be required for combined VSP+DU support.
