[ 05/54] x86-32: Export kernel_stack_pointer() for modules

[Greg Kroah-Hartman]

3.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "H. Peter Anvin" <hpa@xxxxxxxxxxxxxxx>

commit cb57a2b4cff7edf2a4e32c0163200e9434807e0a upstream.

Modules, in particular oprofile (and possibly other similar tools)
need kernel_stack_pointer(), so export it using EXPORT_SYMBOL_GPL().
