| Subject: x86/kexec: add -fno-PIE |
| |
| From: Sebastian Andrzej Siewior <bigeasy@linutronix.de> |
| |
| commit 90944e40ba1838de4b2a9290cf273f9d76bd3bdd upstream. |
| |
| If the gcc is configured to do -fPIE by default then the build aborts |
| later with: |
| | Unsupported relocation type: unknown type rel type name (29) |
| |
| Tagging it stable so it is possible to compile recent stable kernels as |
| well. |
