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? -- Stefan Richter -=====-==--= -==- -===- http://arcgraph.de/sr/ -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
