Subject: [PATCH] fix build on x86_64 with !CONFIG_HOTPLUG_CPU
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d51761233d9e3be4cdf10f7482a50463bbd78c78;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] fix build on x86_64 with !CONFIG_HOTPLUG_CPU

The commit e2c0388866dc12bef56b178b958f9b778fe6c687 added
setup_additional_cpus to setup.c but this is only defined if
CONFIG_HOTPLUG_CPU is set.  This patch changes the #ifdef to reflect that.
