Subject: linux-next: build failure after merge of the Linus' tree

Hi all,

After merging the Linus' tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

kernel/irq/chip.c: In function 'handle_edge_eoi_irq':
kernel/irq/chip.c:517: warning: label 'out_unlock' defined but not used
kernel/irq/chip.c:503: error: label 'out_eoi' used but not defined

Caused by commit 0521c8fbb3da ("genirq: Provide edge_eoi flow handler")
which was clearly not even built with CONFIG_IRQ_EDGE_EOI_HANDLER defined.

I applied this fixup patch:

From: Stephen Rothwell <sfr@...b.auug.org.au>
Date: Wed, 30 Mar 2011 10:55:12 +1100
Subject: [PATCH] genirq: fix CONFIG_IRQ_EDGE_EOI_HANDLER build

Fixes these errors:

kernel/irq/chip.c: In function 'handle_edge_eoi_irq':
kernel/irq/chip.c:517: warning: label 'out_unlock' defined but not used
kernel/irq/chip.c:503: error: label 'out_eoi' used but not defined
