Caused by commit 2b07b4da35a9 ("smpboot: allow passing the cpumask on per-cpu thread registration") I have added the following build faix for today: From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx> Date: Thu, 16 Jul 2015 15:30:05 +1000 Subject: [PATCH] smpboot: fix for allow passing the cpumask on per-cpu thread registration Signed-off-by: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx> --- kernel/smpboot.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/kernel/smpboot.c b/kernel/smpboot.c index d99a41d25b0c..a818cbc73e14 100644 --- a/kernel/smpboot.c +++ b/kernel/smpboot.c @@ -308,7 +308,7 @@ out: put_online_cpus(); return ret; } -EXPORT_SYMBOL_GPL(smpboot_register_percpu_thread); +EXPORT_SYMBOL_GPL(smpboot_register_percpu_thread_cpumask); /** * smpboot_unregister_percpu_thread - Unregister a per_cpu thread related to hotplug -- 2.1.4 -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
