Subject[PATCH 08/21] powerpc: Make function __giveup_fpu static
When CONFIG_PPC_FPU is defined the prototype exposed in asm/switch_to.h is:

extern void giveup_fpu(struct task_struct *);

Change the function prototype of __giveup_fpu to static. Fix warning
(treated as error in W=1):

CC arch/powerpc/kernel/process.o
arch/powerpc/kernel/process.c:176:6: error: no previous prototype for ‘__giveup_fpu’ [-Werror=missing-prototypes]
void __giveup_fpu(struct task_struct *tsk)
cc1: all warnings being treated as errors
