From 1cdf039bf82a39d816ca4b8161b01c0acfca3e62 Mon Sep 17 00:00:00 2001 From: Mathieu Malaterre Date: Sun, 25 Feb 2018 18:22:23 +0100 Subject: [PATCH] powerpc/kernel: Make function __giveup_fpu() static __giveup_fpu() is never called outside process.c, so it can be static. That also means we don't need an empty definition in switch_to.h Signed-off-by: Mathieu Malaterre [mpe: Also drop the empty version, rewrite change log] Signed-off-by: Michael Ellerman --- arch/powerpc/include/asm/switch_to.h | 1 - arch/powerpc/kernel/process.c | 4 ++-- 2 files changed, 2 insertions(+), 3 deletions(-) diff --git a/arch/powerpc/include/asm/switch_to.h b/arch/powerpc/include/asm/switch_to.h index c3ca42cdc9f5..be8c9fa23983 100644 --- a/arch/powerpc/include/asm/switch_to.h +++ b/arch/powerpc/include/asm/switch_to.h @@ -35,7 +35,6 @@ static inline void disable_kernel_fp(void) msr_check_and_clear(MSR_FP); } #else -static inline void __giveup_fpu(struct task_struct *t) { } static inline void save_fpu(struct task_struct *t) { } static inline void flush_fp_to_thread(struct task_struct *t) { } #endif diff --git a/arch/powerpc/kernel/process.c b/arch/powerpc/kernel/process.c index 1738c4127b32..ec4f363ebb89 100644 --- a/arch/powerpc/kernel/process.c +++ b/arch/powerpc/kernel/process.c @@ -173,7 +173,7 @@ void __msr_check_and_clear(unsigned long bits) EXPORT_SYMBOL(__msr_check_and_clear); #ifdef CONFIG_PPC_FPU -void __giveup_fpu(struct task_struct *tsk) +static void __giveup_fpu(struct task_struct *tsk) { unsigned long msr; @@ -556,7 +556,7 @@ void restore_math(struct pt_regs *regs) regs->msr = msr; } -void save_all(struct task_struct *tsk) +static void save_all(struct task_struct *tsk) { unsigned long usermsr;
