Subject: [PATCH 5/7] powerpc/mm: declare some local functions static
Date: Mon, 29 May 2017 17:32:04 +0200 (CEST)	[thread overview]
Message-ID: <8bcba44d31778772e1046302036d618dd7b67729.1496070452.git.christophe.leroy@c-s.fr> (raw)
In-Reply-To: <cover.1496070452.git.christophe.leroy@c-s.fr>

get_pteptr() and __mapin_ram_chunk() are only used locally,
so define them static
