Subject: [PATCH] x86/mm: Remove the redundant conditional check
Date: Sun, 8 Mar 2020 09:35:11 +0800 [thread overview]
Message-ID: <20200308013511.12792-1-bhe@redhat.com> (raw)
In commit f70029bbaacbfa8f0 ("mm, memory_hotplug: drop CONFIG_MOVABLE_NODE"),
the dependency on CONFIG_MOVABLE_NODE was removed for N_MEMORY, so the
conditional check in paging_init() doesn't make any sense any more.
Remove it.
