Subject: [PATCH v6 12/14] arm64/numa: remove some useless code
Date: Thu, 11 Aug 2016 17:33:46 +0800	[thread overview]
Message-ID: <1470908028-8596-13-git-send-email-thunder.leizhen@huawei.com> (raw)
In-Reply-To: <1470908028-8596-1-git-send-email-thunder.leizhen-hv44wF8Li93QT0dZR+AlfA@public.gmane.org>

1. Currently only cpu0 set on cpu_possible_mask and percpu areas have not
   been initialized.
2. No reason to limit cpu0 must belongs to node0.
