Subject: [PATCH 09/21] powerpc: Make function save_all static

Since function `save_all` is not meant to be exported, change the signature
to `static`. Fix warning (treated as error with W=1):

  CC      arch/powerpc/kernel/process.o
arch/powerpc/kernel/process.c:559:6: error: no previous prototype for ‘save_all’ [-Werror=missing-prototypes]
 void save_all(struct task_struct *tsk)
      ^~~~~~~~
cc1: all warnings being treated as errors
