Subject: linux-next: build failure after merge of the final tree (acpi tree
 related)

Hi all,

After merging the final tree, today's linux-next build (sparc64 defconfig)
failed like this:

arch/sparc/include/asm/processor.h: Assembler messages:
arch/sparc/include/asm/processor.h:10: Error: Unknown opcode: `extern'

Caused by commit 3a242f58a5f4 ("sparc idle: rename pm_idle to
sparc_idle") from the acpi tree.

I have applied this patch for today:

From: Stephen Rothwell <sfr@...b.auug.org.au>
Date: Mon, 11 Feb 2013 18:30:19 +1100
Subject: [PATCH] sparc idle: protect variable declarations against the assembler
