Subject: powerpc: add a missing label in resume_kernel
From: Kevin Hao <haokexin@xxxxxxxxx>
commit d8b92292408831d86ff7b781e66bf79301934b99 upstream.
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.
