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:
