Subject: [036/102] irq_work, ppc: Fix up arch hooks

3.0-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Peter Zijlstra <a.p.zijlstra@...llo.nl>

commit 4f8b50bbbe63ae4ec6bea28a90a9a603c745ea71 upstream.

Commit e360adbe29 ("irq_work: Add generic hardirq context
callbacks") fouled up the ppc bit, not properly naming the
arch specific function that raises the 'self-IPI'.
