Subject: [PATCH v2 2/7] MIPS: numa: Remove the unused parent_node() macro
Date: Fri, 1 Sep 2017 10:56:34 +0800 [thread overview]
Message-ID: <1504234599-29533-3-git-send-email-douly.fnst@cn.fujitsu.com> (raw)
In-Reply-To: <1504234599-29533-1-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.
