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

Hi all,

After merging the final tree, today's linux-next build (powerpc
ppc44x_defconfig) failed like this:

arch/powerpc/kernel/ppc_ksyms.c:194:1: error: redefinition of '__kstrtab_do_IRQ'
arch/powerpc/kernel/ppc_ksyms.c:62:1: note: previous definition of '__kstrtab_do_IRQ' was here

Caused by commit f4601ff93980 ("PPC: Export some interrupt handlers").

I applied the following patch for today:

From: Stephen Rothwell <sfr@...b.auug.org.au>
Date: Fri, 27 Apr 2012 15:52:54 +1000
Subject: [PATCH] KVM/PPC: do not export things twice
