The VPDMA (Video Port DMA) as found in devices such as DRA7xx is used for both the Video Processing Engine (VPE) and the Video Input Port (VIP). In preparation for this we need to turn vpdma into its own kernel module. Signed-off-by:

Some CEC adapters will receive messages that they initiated. Add a check that will ignore such messages. Most hardware behaves correctly in this respect, but I have seen adapters that don't, so just filter this out in the framework. Signed-off-by:

The maximum 'Max TMDS Rate' in the HDMI VSDB block is 340 MHz, not 600. Higher rates are advertised in the HDMI Forum VSDB block. So lower the Max TMDS rate in the HDMI VSDB block that the vivid driver uses to 300 MHz, which is typical of most HDMI 1.4b devices. Signed-off-by:

Many lirc drivers have their own receive buffers which are freed on unplug (e.g. ir_lirc_unregister). This means that ir->buf->wait_poll will be freed directly after unplug so do not remove yourself from the wait queue. Signed-off-by:

Eric Biggers authored
With the new (in 4.9) option to use a virtually-mapped stack (CONFIG_VMAP_STACK), stack buffers cannot be used as input/output for the scatterlist crypto API because they may not be directly mappable to struct page. get_crypt_info() was using a stack buffer to hold the output from the encryption operation used to derive the per-file key. Fix it by using a heap buffer. This bug could most easily be observed in a CONFIG_DEBUG_SG kernel because this allowed the BUG in sg_set_buf() to be triggered.

With the new (in 4.9) option to use a virtually-mapped stack (CONFIG_VMAP_STACK), stack buffers cannot be used as input/output for the scatterlist crypto API because they may not be directly mappable to struct page. For short filenames, fname_encrypt() was encrypting a stack buffer holding the padded filename. Fix it by encrypting the filename in-place in the output buffer, thereby making the temporary buffer unnecessary. This bug could most easily be observed in a CONFIG_DEBUG_SG kernel because this allowed the BUG in sg_set_buf() to be triggered. Cc: stable@vger.kernel.org Signed-off-by:
