Hi all, After merging the akpm-current tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: arch/powerpc/platforms/pseries/hotplug-memory.c: In function 'lmb_to_memblock': arch/powerpc/platforms/pseries/hotplug-memory.c:217:14: error: implicit declaration of function 'find_memory_block'; did you mean 'walk_memory_blocks'? [-Werror=implicit-function-declaration] 217 | mem_block = find_memory_block(mem_sect); | ^~~~~~~~~~~~~~~~~ | walk_memory_blocks Caused by commit eca658f58c58 ("drivers/base/memory.c: get rid of find_memory_block()") I have reverted that commit for today. -- Cheers, Stephen Rothwell
