Bisect shows: b4f0d3755c5e9cc86292d5fd78261903b4f23d4a is the first bad commit. commit b4f0d3755c5e9cc86292d5fd78261903b4f23d4a Author: Richard Guy Briggs <rgb@redhat.com> AuthorDate: Tue Mar 4 10:38:06 2014 -0500 Commit: Eric Paris <eparis@redhat.com> CommitDate: Tue Sep 23 16:21:28 2014 -0400 audit: x86: drop arch from __audit_syscall_entry() interface Since the arch is found locally in __audit_syscall_entry(), there is no need pass it in as a parameter. Delete it from the parameter list. x86* was the only arch to call __audit_syscall_entry() directly and did so f assembly code.

Issue reported upstream through LKML: https://lkml.org/lkml/2014/10/22/667
Should be solved by "i386/audit: stop scribbling on the stack frame", which at some point in the future will land on Linus' tree, from the x86/urgent branch, then will get merged by Daniel.
Sorry, change status back to assigned. We can change it until the related patch in Daniel's repo.
