[PATCH 0/2] Syscall auditing lite

I've made no secret of the fact that I dislike syscall auditing. As far as I can tell, the main technical (i.e. not compliance-related) use of syscall auditing is to supply some useful context information to go along with events like AVC denials. CONFIG_AUDITSYSCALL is serious overkill to do this. kernel/auditsc.c is ~2500 lines of terror. This patchset accomplishes the same goal, more usefully, with no overhead at all, in under 70 lines of code. It tries to coexist cleanly with CONFIG_AUDITSYSCALL. This is only implemented for x86. Other architectures can add support fairly easily, I think.
