Hi all,

After merging the akpm-current tree, today's linux-next build (sparc64
defconfig) failed like this:

arch/sparc/mm/init_64.c:2495:4: error: implicit declaration of function 'register_page_bootmem_info_node'; did you mean 'register_page_bootmem_info'? [-Werror=implicit-function-declaration]
    register_page_bootmem_info_node(NODE_DATA(i));
    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    register_page_bootmem_info

Caused by commit

  cd28b1a6791d ("mm: memory_hotplug: factor out bootmem core functions to bootmem_info.c")

grep is your friend ...

I have applied the following patch for today:
