[CVE-2011-3619] apparmor audit DOS

[Andy Whitcroft]

CVE-2011-3619
	A flaw was discovered in the Linux kernel's AppArmor security
	interface when invalid information was written to it. An
	unprivileged local user could use this to cause a denial of
	service on the system.

This problem was introduced in the version of apparmor in maverick.
Fixes for this have hit natty and later via mainline and stable.  Following
this email is a patch for maverick, maverick/ti-omap4 and natty/ti-omap4;
this is a simple cherry-pick from the mainline fix.

Proposing for maverick, maverick/ti-omap4 and natty/ti-omap4.
