From: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Date: Fri, 4 Nov 2016 19:39:40 +0100 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.
