This patch coverts to the common code. (*) df3fd6509421: ALSA: memalloc: Add vmalloc buffer allocation support 6ef6be988f98: ALSA: pcm: Handle special page mapping in the default mmap handler Also, since the SG-buffer-specific PCM ops becomes identical with the normal PCM ops, unify them again to the single ops, too.
