Subject: [PATCH 04/11] MIPS: numa: Remove the unused parent_node() macro
Date: Wed, 26 Jul 2017 21:34:29 +0800	[thread overview]
Message-ID: <1501076076-1974-5-git-send-email-douly.fnst@cn.fujitsu.com> (raw)
In-Reply-To: <1501076076-1974-1-git-send-email-douly.fnst@cn.fujitsu.com>

Commit a7be6e5a7f8d ("mm: drop useless local parameters of
__register_one_node()") removes the last user of parent_node().

The parent_node() macros in both IP27 and Loongson64 are unnecessary.

Remove it for cleanup.
