Actually, this has been a looong-standing problem.
I have a series of patches to fix these issues, but it's more
intensively involved with dma_*() functions.

The patches can be found in test/dma-fix branch of sound GIT tree.
git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git test/dma-fix

This basically adds dma_mmap_coherent() function to feasible
architectures, which is already implemented for ARM, so far.


thanks,

Takashi
