Nicolas pointed out that the cxgb4 driver is doing dma off of the stack, which is generally considered a very bad thing. On some architectures it could be a security problem, but odds are none of them actually run this driver, so it's just a "normal" bug. Resolve this by allocating the memory for a message off of the heap instead of the stack. kmalloc() always will give us a proper memory location that DMA will work correctly from.
