 moduleh tree related)

Hi all,

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

In file included from drivers/dma/iovlock.c:28:0:
include/linux/dmaengine.h: In function '__dma_cap_zero':
include/linux/dmaengine.h:736:2: error: implicit declaration of function 'bitmap_zero'
In file included from include/linux/nodemask.h:95:0,
                 from include/linux/mmzone.h:16,
                 from include/linux/gfp.h:4,
                 from include/linux/mm.h:8,
                 from include/linux/pagemap.h:7,
                 from drivers/dma/iovlock.c:29:
include/linux/bitmap.h: At top level:
include/linux/bitmap.h:159:20: warning: conflicting types for 'bitmap_zero'
include/linux/bitmap.h:159:20: error: static declaration of 'bitmap_zero' follows non-static declaration
include/linux/dmaengine.h:736:2: note: previous implicit declaration of 'bitmap_zero' was here

Presumably caused by some include file no longer being implicitly
included.

I have added the folllowing patch for today:
