From: Kevin Hao Date: Tue, 9 Apr 2013 22:31:24 +0000 (+0000) Subject: powerpc: add a missing label in resume_kernel X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d8b92292408831d86ff7b781e66bf79301934b99;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git powerpc: add a missing label in resume_kernel 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.
