Subject: ARM: smp: remove wrapper functions
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0a301110b7bd33ef10164c184fe2c1d8c4c3ab6b;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ARM: smp: remove wrapper functions

Remove some silly wrapper functions which aren't really required:
	platform_smp_prepare_cpus
	platform_secondary_init
	platform_cpu_die

This simplifies the code.
