From 734b5a0bbdf43518e6739c8156a985e385e557fe Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 23 Nov 2018 19:38:13 +0100 Subject: ALSA: Replace snd_malloc_pages() and snd_free_pages() with standard helpers, take#2 snd_malloc_pages() and snd_free_pages() are merely thin wrappers of the standard page allocator / free functions. Even the arguments are compatible with some standard helpers, so there is little merit of keeping these wrappers. This patch replaces the all existing callers of snd_malloc_pages() and snd_free_pages() with the direct calls of the standard helper functions. In this version, we use a recently introduced one, alloc_pages_exact(), which suits better than the old snd_malloc_pages() implementation for our purposes. Then we can avoid the waste of pages by alignment to power-of-two. Since alloc_pages_exact() does split pages, we need no longer __GFP_COMP flag; or better to say, we must not pass __GFP_COMP to alloc_pages_exact(). So the former unconditional addition of __GFP_COMP flag in snd_malloc_pages() is dropped, as well as in most other places.
