From a52ef778ff28d0782172e4e0b99aeda7bd97dd21 Mon Sep 17 00:00:00 2001 From: Chen Lifu Date: Mon, 29 Mar 2021 11:43:43 +0800 Subject: [PATCH] arm64: smp: Add missing prototype for some smp.c functions MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit In commit eb631bb5bf5b ("arm64: Support arch_irq_work_raise() via self IPIs") a new function "arch_irq_work_raise" was added without a prototype. In commit d914d4d49745 ("arm64: Implement panic_smp_self_stop()") a new function "panic_smp_self_stop" was added without a prototype. We get the following warnings on W=1: arch/arm64/kernel/smp.c:842:6: warning: no previous prototype for ‘arch_irq_work_raise’ [-Wmissing-prototypes] arch/arm64/kernel/smp.c:862:6: warning: no previous prototype for ‘panic_smp_self_stop’ [-Wmissing-prototypes] Fix the warnings by: 1. Adding the prototype for 'arch_irq_work_raise' in irq_work.h 2. Adding the prototype for 'panic_smp_self_stop' in smp.h Signed-off-by: Chen Lifu Link: https://lore.kernel.org/r/20210329034343.183974-1-chenlifu@huawei.com Signed-off-by: Catalin Marinas --- arch/arm64/include/asm/irq_work.h | 2 ++ arch/arm64/include/asm/smp.h | 1 + 2 files changed, 3 insertions(+) diff --git a/arch/arm64/include/asm/irq_work.h b/arch/arm64/include/asm/irq_work.h index a102028..81bbfa3 100644 --- a/arch/arm64/include/asm/irq_work.h +++ b/arch/arm64/include/asm/irq_work.h @@ -2,6 +2,8 @@ #ifndef __ASM_IRQ_WORK_H #define __ASM_IRQ_WORK_H +extern void arch_irq_work_raise(void); + static inline bool arch_irq_work_has_interrupt(void) { return true; diff --git a/arch/arm64/include/asm/smp.h b/arch/arm64/include/asm/smp.h index bcb01ca..0e35775 100644 --- a/arch/arm64/include/asm/smp.h +++ b/arch/arm64/include/asm/smp.h @@ -145,6 +145,7 @@ bool cpus_are_stuck_in_kernel(void); extern void crash_smp_send_stop(void); extern bool smp_crash_stop_failed(void); +extern void panic_smp_self_stop(void); #endif /* ifndef __ASSEMBLY__ */ -- 2.7.4
