-Hi,
-I post this patch that fixes a kernel crash that happens when using a dvb
-usb stick on a mips platform and I think even on other platforms on which
-the dma access in not cache-coherent.
-
-The problem's origin is that, inside the method usb_bulk_urb_init of file
-drivers/media/dvb/dvb-usb/usb-urb.c, stream->urb_list[i]->transfer_buffer
-points to a memory area that has been allocated to be dma-coherent but
-stream->urb_list[i]->transfer_flags doesn't include the
-URB_NO_TRANSFER_DMA_MAP flag and stream->urb_list[i]->transfer_dma is not
-set.
-When later on the stream->urb_list[i]->transfer_buffer pointer is used
-inside function usb_hcd_submit_urb of file drivers/usb/core/hcd.c since the
-flag URB_NO_TRANSFER_DMA_MAP is not set the urb->transfer_buffer pointer is
-passed to the dma_map_single function that since the address is dma-coherent
-returns a wrong tranfer_dma address that later on leads to the kernel crash.
-
-The problem is solved by setting the URB_NO_TRANSFER_DMA_MAP flag and the
-stream->urb_list[i]->transfer_dma address.
-
-Perhaps to be more safe the URB_NO_TRANSFER_DMA_MAP flag can be set only
-if stream->urb_list[i]->transfer_dma != 0.
-
-I don't know if half of the fault can be of the dma_map_single function that
-should anyway returns a valid address both for a not dma-coherent and a
-dma-coherent address.
-
-Just to be clear:
-I've done this patch to solve my problem and I tested it only on a mips 
-platform
-but I think it should not cause any problems on other platforms.
-I posted it here to help someone else that can have my same problem and to 
-point it out
-to the mantainer of this part of code.
-You can use it at your own risk and I'm not resposible in any way for any 
-problem or
-damage that it can cause.
-I'm available to discuss about it
-
-Bye
-
-Michele Scorcia

-From: "Woodruff, Richard" <r-woodruff2 at ti.com>
-
-In my device I get many interrupts from a high speed USB device in a very
-short period of time.  The system spends a lot of time reprogramming the
-hardware timer which is in a slower timing domain as compared to the CPU. 
-This results in the CPU spending a huge amount of time waiting for the
-timer posting to be done.  All of this reprogramming is useless as the
-wake up time has not changed.
-
-As measured using ETM trace this drops my reprogramming penalty from
-almost 60% CPU load down to 15% during high interrupt rate.  I can send
-traces to show this.
-
-
-Suppress setting of duplicate timer event when timer already stopped. 
-Timer programming can be very costly and can result in long cpu stall/wait
-times.

-Subject: [FYI PATCH] ASOC:TWL4030 Audio capture fix
-
-A couple of folks have noticed an issue with audio capture -- the
-capture result is always silence.
-
-The patch below is a quick fix for those with this issue.  There are
-substantial changes to the codec driver that will be trickling down
-from ASoC, and they deal with this issue differently.
-
-So consider this as a bandaid for those who don't want to wait for the
-trickle down :-)
