From 3aae97c8b1dbefb23217d193e2818d1490651c95 Mon Sep 17 00:00:00 2001 From: Alexandre Courbot Date: Fri, 23 May 2014 09:23:32 +0900 Subject: ARM: trusted_foundations: fix compile error on non-SMP The setup_max_cpus variable is only defined if CONFIG_SMP is set. Add a preprocessor condition to avoid the following compilation error if CONFIG_SMP is not set: arch/arm/include/asm/trusted_foundations.h: In function 'register_trusted_foundations': arch/arm/include/asm/trusted_foundations.h:57:2: error: 'setup_max_cpus' undeclared (first use in this function) Signed-off-by: Alexandre Courbot Reported-by: Russell King Acked-by: Stephen Warren Signed-off-by: Arnd Bergmann --- arch/arm/include/asm/trusted_foundations.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'arch/arm/include/asm') diff --git a/arch/arm/include/asm/trusted_foundations.h b/arch/arm/include/asm/trusted_foundations.h index b5f7705abcb0..624e1d436c6c 100644 --- a/arch/arm/include/asm/trusted_foundations.h +++ b/arch/arm/include/asm/trusted_foundations.h @@ -54,7 +54,9 @@ static inline void register_trusted_foundations( */ pr_err("No support for Trusted Foundations, continuing in degraded mode.\n"); pr_err("Secondary processors as well as CPU PM will be disabled.\n"); +#if IS_ENABLED(CONFIG_SMP) setup_max_cpus = 0; +#endif cpu_idle_poll_ctrl(true); } -- cgit v1.2.1
