  Impact: allow architectures to monitor busses for dma mem leakage

  This patch adds checking code to detect if a device has pending DMA
  operations when it is about to be unbound from its device driver.

• ac26c18bd   dma-debug: add function to dump dma mappings ... Browse Code »

  This adds a function to dump the DMA mappings that the debugging code is
  aware of -- either for a single device, or for _all_ devices.

  This can be useful for debugging -- sticking a call to it in the DMA
  page fault handler, for example, to see if the faulting address _should_
  be mapped or not, and hence work out whether it's IOMMU bugs we're
  seeing, or driver bugs.
