Re: [PATCH 15/21] powerpc: Add missing prototype for MMU_setup

Mathieu Malaterre [off-list ref] writes:

Add a function declaration for MMU_setup at the beginning of the file to
fix a warning (treated as error in W=3D1):

  CC      kernel/sys.o
arch/powerpc/mm/init_32.c:102:13: error: no previous prototype for =E2=80=

=98MMU_setup=E2=80=99 [-Werror=3Dmissing-prototypes]

 void __init MMU_setup(void)
             ^~~~~~~~~
cc1: all warnings being treated as errors

Can't it be static instead?

  $ git grep -n MMU_setup
  arch/powerpc/mm/init_32.c:102:void __init MMU_setup(void)
  arch/powerpc/mm/init_32.c:135:  MMU_setup();
