ALSA: aloop: Convert to the common vmalloc memalloc
The recent change (*) in the ALSA memalloc core allows us to drop the special vmalloc-specific allocation and page handling. This patch coverts to the common code. (*) 1fe7f397cfe2: ALSA: memalloc: Add vmalloc buffer allocation support 7e8edae39fd1: ALSA: pcm: Handle special page mapping in the default mmap handler Link: https://lore.kernel.org/r/20191105151856.10785-10-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
