I changed the dma buffers to use allocated memory instead of stack
memory.
The reason for this is documented in Documentation/DMA-API-HOWTO.txt
under the section: "What memory is DMA'able?" That document was only
added a couple weeks ago and there are still lots of modules which
haven't been corrected yet. Btw. Smatch includes a pretty good test to
find places which use stack memory as a dma buffer. That's how I found
these. (http://smatch.sf.net).
