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

Hi all,

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

arch/sparc/kernel/setup_64.c: In function 'start_early_boot':
arch/sparc/kernel/setup_64.c:382:9: error: implicit declaration of function 'time_init_early'; did you mean 'inode_init_early'? [-Werror=implicit-function-declaration]
  382 |         time_init_early();
      |         ^~~~~~~~~~~~~~~
      |         inode_init_early

Presumably caused by commit

  c16caa9110dd ("init: consolidate prototypes in linux/init.h")

I applied this partial revert:

Subject: [PATCH] fix up for "init: consolidate prototypes in linux/init.h"
