[CVE-2011-1759] semtimedop nops overflow

[Andy Whitcroft]

CVE-2011-1759
	When CONFIG_OABI_COMPAT is set, the wrapper for semtimedop does
	not bound the nsops argument. A sufficiently large value will
	cause an integer overflow in allocation size, followed by copying
	too much data into the allocated buffer.

Fixes for this have hit oneiric and later via mainline and stable.
Following this email is a patch for maverick/ti-omap4 and natty/ti-omap4,
this is a simple cherry-pick from mainline.

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