Commit be95485a0b828 was incorrectly backported to 3.18 and now causes a different build error when CONFIG_SMP is disabled: arch/arm/kernel/psci.c:287:12: error: redefinition of 'psci_init' This version is how it should be on 3.18, with the main psci code built for both SMP and UP, but the psci_smp_available() function only being available for SMP builds. Fixes: dbcfee724255 ("ARM: 8457/1: psci-smp is built only for SMP") Signed-off-by: Arnd Bergmann <arnd@xxxxxxxx> --- arch/arm/include/asm/psci.h | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff --git a/arch/arm/include/asm/psci.h b/arch/arm/include/asm/psci.h index e3789fb02c9c..8ca5308a05d7 100644 --- a/arch/arm/include/asm/psci.h +++ b/arch/arm/include/asm/psci.h @@ -37,11 +37,15 @@ struct psci_operations { extern struct psci_operations psci_ops; extern struct smp_operations psci_smp_ops; -#if defined(CONFIG_SMP) && defined(CONFIG_ARM_PSCI) +#ifdef CONFIG_ARM_PSCI int psci_init(void); -bool psci_smp_available(void); #else static inline int psci_init(void) { return 0; } +#endif + +#if defined(CONFIG_SMP) && defined(CONFIG_ARM_PSCI) +bool psci_smp_available(void); +#else static inline bool psci_smp_available(void) { return false; } #endif -- 2.9.0
