I am looking for a solution to a similar problem. I am writing a
driver for an FCC on the 8260 in transparent mode, and need
to allocate buffer memory. The buffer memory will get filled
via DMA, and therefore must not be cached. Will the following work

	vaddr = kmalloc(BUF_SIZE, GFP_DMA);
	paddr = __pa(vaddr);

monkman at jump.net    looking for the truth," and so it goes away. Puzzling.
