From: Ralf Baechle <r...@linux-mips.org>
include/drm/ttm/ttm_memory.h uses struct page * without having included
the required headers or a forward declaration resulting in the following
build error for mtx1_defconfig on Linus' master branch, possibly others:
CC [M] drivers/gpu/drm/ttm/ttm_memory.o
In file included from drivers/gpu/drm/ttm/ttm_memory.c:28:

`ttm_mem_global_free_page'
include/drm/ttm/ttm_memory.h:155: note: previous declaration of
`ttm_mem_global_free_page' was here
Fixed by adding a forward declaration.
