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

Hi Andrew,

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

fs/binfmt_elf.c: In function 'fill_files_note':
fs/binfmt_elf.c:1419:2: error: implicit declaration of function 'vmalloc' [-Werror=implicit-function-declaration]
fs/binfmt_elf.c:1419:7: warning: assignment makes pointer from integer without a cast [enabled by default]
fs/binfmt_elf.c:1437:5: error: implicit declaration of function 'vfree' [-Werror=implicit-function-declaration]

Caused by commit "coredump: extend core dump note section to contain file
names of mapped files".  Forgot to include vmalloc.h :-(

I added this patch for today:
