From df7ffa34cc0c06bfa7206732df78725ff34633ee Mon Sep 17 00:00:00 2001 From: Zhen Lei Date: Thu, 1 Sep 2016 14:55:03 +0800 Subject: arm64/numa: remove some useless code When the deleted code is executed, only the bit of cpu0 was set on cpu_possible_mask. So that, only set_cpu_numa_node(0, NUMA_NO_NODE); will be executed. And map_cpu_to_node(0, 0) will soon be called. So these code can be safely removed.
