From 969ff73e72fe903a2354c51e01c1a1f937c544ca Mon Sep 17 00:00:00 2001 From: Dou Liyang Date: Wed, 26 Jul 2017 21:34:26 +0800 Subject: [PATCH] arm64: numa: Remove the unused parent_node() macro Commit a7be6e5a7f8d ("mm: drop useless local parameters of __register_one_node()") removes the last user of parent_node(). The parent_node() macro in ARM64 platform is unnecessary. Remove it for cleanup.
