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: NAlexandre Courbot <acourbot@nvidia.com> Reported-by: NRussell King <rmk+kernel@arm.linux.org.uk> Acked-by: NStephen Warren <swarren@nvidia.com> Signed-off-by: NArnd Bergmann <arnd@arndb.de>
