X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6721f77810dfcb7cbf8e97be6fa43fe2740dd0aa;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git [S390] Fix cpu hotplug (missing 'online' attribute). 72486f1f8f0a2bc828b9d30cf4690cf2dd6807fc inverts the logic if an 'online' attribute in /sys/devices/system/cpu/cpuX should appear. So we end up with no hotpluggable cpus at all... Set the hotpluggable value to one to make sure the online attribute appears again.
