Subject: [ARM] SMP: don't set cpu_*_map in smp_prepare_boot_cpu
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=091c539f08a6700e0cca8cd620c3d72dd9f9e2bb;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[ARM] SMP: don't set cpu_*_map in smp_prepare_boot_cpu

The recent addition of boot_cpu_init() implements the initialisation
of the online, present and possible cpu maps for the boot CPU, so
there is no reason to duplicate this in the architecture
smp_prepare_boot_cpu() hook.
