Subject: [PATCH] powerpc: add a missing label in resume_kernel

From: Kevin Hao <[email-masked]>
Date: Wed, 10 Apr 2013 16:31:24 +0800

A label 0 was missed in the patch a9c4e541 (powerpc/kprobe: Complete
kprobe and migrate exception frame). This will cause the kernel
branch to an undetermined address if there really has a conflict when
updating the thread flags.
