Impact: build fix
Fix:
arch/x86/kvm/x86.o: In function `dma_debug_add_bus':
(.text+0x0): multiple definition of `dma_debug_add_bus'
dma_debug_add_bus() should be a static inline function.

dma-debug: add a check dma memory leaks2009-03-17T11:56:49+00:00Joerg Roedeljoerg.roedel@amd.com2009-03-16T16:32:14+00:00urn:sha1:41531c8f5f05aba5ec645d9770557eedbf75b422
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.

dma-debug: add function to dump dma mappings2009-03-17T11:56:39+00:00David Woodhousedwmw2@infradead.org2009-02-12T15:19:13+00:00urn:sha1:ac26c18bd35d982d1ba06020a992b1085fefc3e2
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.
