Date: Tue, 23 Apr 2013 14:51:59 -0700 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Kevin Hao <haokexin@...il.com>, Tiejun Chen <tiejun.chen@...driver.com>, Stephen Rothwell <sfr@...b.auug.org.au> Subject: [ 01/42] powerpc: add a missing label in resume_kernel 3.8-stable review patch. If anyone has any objections, please let me know. ------------------ From: Kevin Hao <haokexin@...il.com> 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.
