[PATCH v2] arm64: topology: Avoid checking numa mask for scheduler MC selection

2018-06-06 Thread Jeremy Linton
The numa mask subset check can often lead to system hang or crash during CPU hotplug and system suspend operation if NUMA is disabled. This is mostly observed on HMP systems where the CPU compute capacities are different and ends up in different scheduler domains. Since cpumask_of_node is returned
