[0/8] ALSA: non-cached memalloc helper

Message

Hi,

this is a patchset to add the non-cached page handling in the memory
allocation helpers, which have been implemented individually in
several driver codes.  This also fixes a long-time bug of HD-audio
non-mmap behavior in the non-snoop mode, which was reported recently.
