soft_nmi_interrupt() usage requires PPC_WATCHDOG to be configured. Check the CONFIG definition to declare the prototype.
It fixes this W=1 compile error : ../arch/powerpc/kernel/watchdog.c:250:6: error: no previous prototype for ‘soft_nmi_interrupt’ [-Werror=missing-prototypes] 250 | void soft_nmi_interrupt(struct pt_regs *regs) | ^~~~~~~~~~~~~~~~~~ Cc: Nicholas Piggin <npig...@gmail.com> Signed-off-by: Cédric Le Goater <c...@kaod.org> --- arch/powerpc/include/asm/nmi.h | 1 + arch/powerpc/kernel/watchdog.c | 1 + 2 files changed, 2 insertions(+) diff --git a/arch/powerpc/include/asm/nmi.h b/arch/powerpc/include/asm/nmi.h index 84b4cfe73edd..63eccea93796 100644 --- a/arch/powerpc/include/asm/nmi.h +++ b/arch/powerpc/include/asm/nmi.h @@ -4,6 +4,7 @@ #ifdef CONFIG_PPC_WATCHDOG extern void arch_touch_nmi_watchdog(void); +void soft_nmi_interrupt(struct pt_regs *regs); #else static inline void arch_touch_nmi_watchdog(void) {} #endif diff --git a/arch/powerpc/kernel/watchdog.c b/arch/powerpc/kernel/watchdog.c index af3c15a1d41e..3ae13c2a10cf 100644 --- a/arch/powerpc/kernel/watchdog.c +++ b/arch/powerpc/kernel/watchdog.c @@ -27,6 +27,7 @@ #include <linux/smp.h> #include <asm/paca.h> +#include <asm/nmi.h> /* * The powerpc watchdog ensures that each CPU is able to service timers. -- 2.26.2
