ALSA: memalloc: Support for non-coherent page allocation
Following to the addition of non-contiguous pages, this patch adds the new contiguous non-coherent page allocation to the standard memalloc helper. Like the previous non-contig type, this non-coherent type is also directional and requires the explicit sync, too. Hence the driver using this type of buffer may need to set SNDRV_PCM_INFO_EXPLICIT_SYNC flag to the PCM hardware.info as well, unless it's set up in the managed mode.
