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:

mm/cma.c: In function 'cma_declare_contiguous':
mm/cma.c:288:4: error: implicit declaration of function 'phys_to_virt' [-Werror=implicit-function-declaration]
    kmemleak_ignore(phys_to_virt(addr));
    ^

Caused by commit 2a70e5a78672 ("mm/cma: ake kmemleak ignore CMA regions").

I added the following fix patch:
