Subject: lib/percpu_counter.c: enclose hotplug only variables in hotplug ifdef
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3a8495c739c1c773181a246dbb7c12b5b67a8325;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

lib/percpu_counter.c: enclose hotplug only variables in hotplug ifdef

These variables are only used when CONFIG_HOTPLUG_CPU is enabled, they are
ifdef'ed everywhere else.  So don't define them when CONFIG_HOTPLUG_CPU is
not enabled.
