3.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: "H. Peter Anvin" <hpa@linux.intel.com>
commit cb57a2b4cff7edf2a4e32c0163200e9434807e0a upstream.
Modules, in particular oprofile (and possibly other similar tools) need kernel_stack_pointer(), so export it using EXPORT_SYMBOL_GPL().
