[PATCH v8 12/16] arm64/numa: remove some useless code

From: Zhen Lei
Date: Thu Sep 01 2016 - 02:59:53 EST


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.
