JIRA: https://issues.redhat.com/browse/RHEL-14156 commit 1bfaa37fd3486e66131de9cb87747c84b4c89a05 Author: Jiri Slaby (SUSE) <jirislaby@kernel.org> Date: Mon Oct 30 12:34:16 2023 +0100 kbuild: dummy-tools: pretend we understand -fpatchable-function-entry Commit 0f71dcfb4aef ("powerpc/ftrace: Add support for -fpatchable-function-entry") added a script to check for -fpatchable-function-entry compiler support. The script expects compiler to emit the section __patchable_function_entries and few nops after a function entry. If the compiler understands and emits the above, CONFIG_ARCH_USING_PATCHABLE_FUNCTION_ENTRY is set. So teach dummy-tools' gcc about this.
