[CVE-2011-2182] LDM heap overflow

[Andy Whitcroft]

CVE-2011-2182
	fs/partitions: Kernel heap overflow via corrupted LDM partition
	tables.  Different issue than CVE-2011-1017

Fixes for this issue have hit lucid and later via mainline and
stable.  Following this email is a patch for hardy, lucid/fsl-imx51,
maverick/ti-omap4, and natty/ti-omap4; this is a simple cherry pick from
the mainline fix.  Note we are including lucid/fsl-imx51 as there is
potential for a local root exploit from this issue.

Proposing for hardy, lucid/fsl-imx51, maverick/ti-omap4, and natty/ti-omap4.
