[alsa-devel] [PATCH 0/5] PCM mmap (temporary) fixes for non-coherent architectures

this is a patchset to fix Oopses from ALSA PCM core with mmap on MIPS
and PPC non-coherent architectures.  This contains also a clean-up for
ARM mmap.

In this patch series, I don't try to port dma_mmap_coherent() to these
architectures yet, but just put ugly ifdefs in the ALSA core side.
Understand that this is a first step forward to a more cleaner solution,
and the purpose right now is just to fix up long-standing Oops.
I'll try to push dma_mmap_coherent() patches for the next kernel once
again after this gets merged.

Since the changes are minimal, I'd like to put them in ASAP for 2.6.33.
Please review and give feedbacks if any problem is found.
