Subject[RFC][PATCH 9/11] security: AppArmor - Audit changes
This patch adds AppArmor support to the audit subsystem.

It creates id 1500 (already included in the the upstream auditd package) for
AppArmor messages.

It also exports the audit_log_vformat function (analagous to having both
printk and vprintk exported).

Signed-off-by: Tony Jones <tonyj@suse.de>
