dma-debug: check_for_stack background?

[Stefan Richter]

Hi,

it took a while but I finally noticed that the DMA debug facility warns 
about mappings of on-stack memory.  What's the problem with that?  Are 
there architectures which don't support such mappings, or is it a 
question of caution not to DMA-map the stack?
