Subject: [PATCH] mm/ksm: make function stable_node_dup static

From: Colin Ian King <colin.king@...onical.com>

The function stable_node_dup is local to the source and does not need
to be in global scope, so make it static.

Cleans up sparse warning:
mm/ksm.c:1321:13: warning: symbol 'stable_node_dup' was not
declared. Should it be static?
