Subject: [PATCH 2/3] mm, treewide: make get_free_pages() and friends return void *
From: "Mike Rapoport (Microsoft)" <rppt@...nel.org>
Vast majority of allocations that use get_free_pages() and it's
derivatives cast the returned value to a pointer type.
Make get_free_pages() and it derivatives return 'void *' with the exception of __get_dma_pages() whose callers all expect an unsigned long.
The call sites are updated with the semantic patch below and a bit of
manual tweaking.
