    arm64: read enable-method for CPU0 · e8765b26
    Mark Rutland authored
    With the advent of CPU_HOTPLUG, the enable-method property for CPU0 may
    tells us something useful (i.e. how to hotplug it back on), so we must
    read it along with all the enable-method for all the other CPUs.  Even
    on UP the enable-method may tell us useful information (e.g. if a core
    has some mechanism that might be usable for cpuidle), so we should
    always read it.
    This patch factors out the reading of the enable method, and ensures
    that CPU0's enable method is read regardless of whether the kernel is
    built with SMP support.
