From 9d26024c964718c6307a96f387b24fc06dac4d91 Mon Sep 17 00:00:00 2001 From: Markos Chandras Date: Tue, 16 Sep 2014 13:57:08 +0100 Subject: [PATCH] MIPS: idle: Remove leftover __pastwait symbol and its references The __pastwait symbol was only used by the address_is_in_r4k_wait_irqoff function but this is no longer used since the SMTC removal in commit b633648c5ad3 ('MIPS: MT: Remove SMTC support'). That symbol also led to build failures under certain random configuration due to the way the compiler compiled the r4k_wait_irqoff function. If that function was called multiple times, the __pastwait symbol was redefined breaking the build like this: CHK include/generated/compile.h CC arch/mips/kernel/idle.o {standard input}: Assembler messages: {standard input}:527: Error: symbol `__pastwait' is already defined Link: http://www.linux-mips.org/cgi-bin/mesg.cgi?a=linux-mips&i=1244879922.24479.30.camel%40falcon Signed-off-by: Markos Chandras Cc: linux-mips@linux-mips.org Cc: Markos Chandras Patchwork: https://patchwork.linux-mips.org/patch/7791/ Signed-off-by: Ralf Baechle --- arch/mips/include/asm/idle.h | 7 ------- arch/mips/kernel/idle.c | 3 --- 2 files changed, 10 deletions(-) diff --git a/arch/mips/include/asm/idle.h b/arch/mips/include/asm/idle.h index d9f932de80e9..1c967abd545c 100644 --- a/arch/mips/include/asm/idle.h +++ b/arch/mips/include/asm/idle.h @@ -8,19 +8,12 @@ extern void (*cpu_wait)(void); extern void r4k_wait(void); extern asmlinkage void __r4k_wait(void); extern void r4k_wait_irqoff(void); -extern void __pastwait(void); static inline int using_rollback_handler(void) { return cpu_wait == r4k_wait; } -static inline int address_is_in_r4k_wait_irqoff(unsigned long addr) -{ - return addr >= (unsigned long)r4k_wait_irqoff && - addr < (unsigned long)__pastwait; -} - extern int mips_cpuidle_wait_enter(struct cpuidle_device *dev, struct cpuidle_driver *drv, int index); diff --git a/arch/mips/kernel/idle.c b/arch/mips/kernel/idle.c index 09ce45980758..0b9082b6b683 100644 --- a/arch/mips/kernel/idle.c +++ b/arch/mips/kernel/idle.c @@ -68,9 +68,6 @@ void r4k_wait_irqoff(void) " wait \n" " .set pop \n"); local_irq_enable(); - __asm__( - " .globl __pastwait \n" - "__pastwait: \n"); } /*
