| Subject: x86-32: Export kernel_stack_pointer() for modules |
| |
| 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(). |
