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

Hi Andrew,

After merging the akpm-current tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

fs/fat/inode.c: In function 'fat_direct_IO':
fs/fat/inode.c:252:2: error: implicit declaration of function 'iov_iter_count' [-Werror=implicit-function-declaration]
  size_t count = iov_iter_count(iter);
  ^

Caused by commit be33247df543 ("fs/fat: remove unnecessary includes").
Removing include files deemed "unnecessary" is fraught.  Please see
Rule 1 in Documentation/SubmitChecklist.

I have added the following fix patch for today:
