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 <acourbot@nvidia.com> Reported-by: Russell King <rmk+kernel@arm.linux.org.uk> --- Hi Stephen,
This patch has been originally submitted through Russell's patch tracker, where it has stayed untouched for ~3 weeks now. Considering that this fixes a compilation error and should thus be made available quickly, and that Tegra is the only user of Trusted Foundations, would you agree to take it into your tree?
