Hi all,

After merging the tip tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

drivers/power/reset/sc27xx-poweroff.c: In function 'sc27xx_poweroff_shutdown':
drivers/power/reset/sc27xx-poweroff.c:38:4: error: implicit declaration of function 'cpu_down' [-Werror=implicit-function-declaration]
   38 |    cpu_down(cpu);
      |    ^~~~~~~~

Caused by commit

  33c3736ec888 ("cpu/hotplug: Hide cpu_up/down()")

interacting with commit

  274afbc3ad33 ("power: reset: sc27xx: Change to use cpu_down()")

from the battery tree.

I have added the following merge fix patch:
