Subject: linux-next: manual merge of the ftrace tree with Linus' tree

Hi Steven,

Today's linux-next merge of the ftrace tree got a conflict in
kernel/trace/ftrace.c between commit b67bfe0d42ca ("hlist: drop the node
parameter from iterators") from Linus' tree and commit f1943977e664
("tracing: Get rid of unneeded key calculation in ftrace_hash_move()")
and e1df4cb682ab ("ftrace: Fix function probe to only enable needed
functions") from the ftrace tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
