Hi, this is a revised patchset that is created from the latest code. The previous one caused a slight conflict with the recent changes, also some patch descriptions have been updated. *** Here is a patch set to add the support for non-contiguous and non-coherent page allocations to the ALSA core memalloc helpers. Currently no driver is using, but this also gave a nice cleanup for the existing SG-buffer helpers on x86.
