[PATCH 3/3] powerpc: perf_event: Hide iseries_check_pending_irqs
From: Anton Blanchard <hidden>
Date: 2009-10-18 11:24:29
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. Signed-off-by: Anton Blanchard <redacted> -- Index: linux.trees.git/arch/powerpc/kernel/entry_64.S ===================================================================
