Subject: [PATCH 2/15] powerpc: don't export static symbol

From: Julia Lawall <Julia.Lawall@...6.fr>

The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r@
type T;
identifier f;
@@

static T f (...) { ... }

@@
identifier r.f;
declarer name EXPORT_SYMBOL;
@@

-EXPORT_SYMBOL(f);
// </smpl>

Furthermore, the function is never used, so its definition is dropped as
well.

Signed-off-by: Julia Lawall <Julia.Lawall@...6.fr>
