Subject: [PATCH 3/3] powerpc: perf_event: Hide iseries_check_pending_irqs

From: Anton Blanchard <[email-masked]>
Date: Sun, 18 Oct 2009 22:24:29 +1100

If CONFIG_PPC_ISERIES isn't defined we end up with iseries_check_pending_irqs
and do_work at the same address. perf ends up picking
iseries_check_pending_irqs which creates confusing backtraces. Hide it.
