| Subject: x86/process: Re-export start_thread() |
| |
| From: Rian Hunter <rian@alum.mit.edu> |
| |
| commit dc76803e57cc86589c4efcb5362918f9b0c0436f upstream. |
| |
| The consolidation of the start_thread() functions removed the export |
| unintentionally. This breaks binfmt handlers built as a module. |
| |
| Add it back. |
| |
| Fixes: e634d8fc792c ("x86-64: merge the standard and compat start_thread() functions") |
