Subject: linux-next: build failure after merge of the nfs tree

Hi Trond,

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

fs/nfs/blocklayout/extent_tree.c: In function 'ext_tree_prepare_commit':
fs/nfs/blocklayout/extent_tree.c:540:3: error: implicit declaration of function '__vmalloc' [-Werror=implicit-function-declaration]
   start_p = __vmalloc(buffer_size, GFP_NOFS, PAGE_KERNEL);
fs/nfs/blocklayout/extent_tree.c:540:11: warning: assignment makes pointer from integer without a cast
   start_p = __vmalloc(buffer_size, GFP_NOFS, PAGE_KERNEL);

Caused by commit 34dc93c2fc04 ("pnfs/blocklayout: allocate separate
pages for the layoutcommit payload").

I added the following fix patch for today:
