Subject: [PATCH v1 13/15] powerpc/mm: refactor pgtable freeing functions on nohash
Date: Wed, 3 Apr 2019 20:06:25 +0000 (UTC) [thread overview]
Message-ID: <d7cfc093d5516600c1df5e1ae052db46af506353.1554321743.git.christophe.leroy@c-s.fr> (raw)
In-Reply-To: <cover.1554321743.git.christophe.leroy@c-s.fr>
pgtable_free() and others are identical on nohash/32 and 64,
so move them into asm/nohash/pgalloc.h
Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>
