From: Arnd Bergmann Date: Thu, 30 Jun 2016 12:25:19 +0000 (+0200) Subject: ARM: shmobile: don't call platform_can_secondary_boot on UP X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=869ec056fa8450184423c8076e0a342db127795c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ARM: shmobile: don't call platform_can_secondary_boot on UP For rcar-gen2, we build the SMP files even for UP configurations, and that just broke: arch/arm/mach-shmobile/built-in.o: In function `shmobile_smp_init_fallback_ops': pm-rcar-gen2.c:(.init.text+0x40c): undefined reference to `platform_can_secondary_boot' This adds an compile-time check before the call to platform_can_secondary_boot, turning the function into an empty stub for UP configurations.
