linux-next: build failure after merge of the drm-intel tree

[Stephen Rothwell]

Hi all,

After merging the drm-intel tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

In file included from drivers/gpio/gpiolib-of.c:19:0:
include/linux/io-mapping.h:115:31: fatal error: asm/pgtable_types.h: No such 
file or directory
In file included from drivers/gpu/drm/nouveau/include/nvif/os.h:16:0,

                 from drivers/gpu/drm/nouveau/include/nvkm/core/object.h:3,   
                 from drivers/gpu/drm/nouveau/include/nvkm/core/client.h:3,   
                 from drivers/gpu/drm/nouveau/nvkm/core/client.c:24:
include/linux/io-mapping.h:115:31: fatal error: asm/pgtable_types.h: No such 
file or directory

and many more.

Caused by commit

  cafaf14a5d8f ("io-mapping: Always create a struct to hold metadata about the 
io-mapping")

I have used the drm-intel tree from next-20160822 for today.
