[PATCH 00/15] ALSA: Improved WC memory handling

[Takashi Iwai]

Hi,

this is a patchset to enhance the ALSA memory allocation helper to
support the allocation of WC pages more generically as well as
supporting the fixed size buffer allocation.  It allows us to reduce
lots of redundant code in various ASoC drivers that still haven't used
the standard preallocation.
