Subject: linux-next: build failure after merge of the final tree (Linus' tree related)

Hi Linus,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/gpu/drm/ttm/ttm_page_alloc.c: In function 'set_pages_a
rray_wb':
drivers/gpu/drm/ttm/ttm_page_alloc.c:227: error: implicit declaration of function 'unmap_page_from_agp'
drivers/gpu/drm/ttm/ttm_page_alloc.c: In function 'set_pages_array_wc':
drivers/gpu/drm/ttm/ttm_page_alloc.c:238: error: implicit declaration of function 'map_page_into_agp'

Presumably caused by commit 1e8655f87333def92bb8215b423adc65403b08a5
("drm/ttm: Fix build on architectures without AGP") as unmap_page_from_agp()
is declared in asm/agp.h.

I have applied the following patch for today:

Subject: [PATCH] drm/ttm: really fix build on architectures without AGP

After commit 1e8655f87333def92bb8215b423adc65403b08a5
("drm/ttm: Fix build on architectures without AGP") was merged, linux-next
got this build failure for a powerpc allyesconfig build:

drivers/gpu/drm/ttm/ttm_page_alloc.c: In function 'set_pages_a
rray_wb':
drivers/gpu/drm/ttm/ttm_page_alloc.c:227: error: implicit declaration of function 'unmap_page_from_agp'
