	A flaw was found in the b43 driver in the Linux kernel. If
	a system had an active wireless interface that uses the b43
	driver, an attacker able to send a specially-crafted frame to
	that interface could cause a denial of service.

Fixes for everything but hardy, lucid/fsl-imx51 and maverick/ti-omap4
have arrived via mainline and stable.  lucid/fsl-imx51 is not longer
supported generally and as the buildds do not contain this hardware is
moved ignored.  Following this email are two patch sets, one for hardy and
one for maverick/ti-omap4.  The hardy patchset contains one pre-requisite
patch and the main patch is a minor backport.  The maverick/ti-omap4
patch is a simple cherry pick from mainline.

Proposing for hardy and maverick/ti-omap4.
