Could me update the title if there are more > suggestions then? How about this? 2/4: kernel hacking: add a config option to disable compiler auto-inlining 3/4: ARM: mm: fix build error in fix_to_virt with -Og optimization level 4/4: kernel hacking: support building kernel with -Og optimization level (The CONFIG name is so long that the subject would easily exceeds 80-columns with it.) I applied this series to linux-kbuild, and will send another pull request in this MW. If you come up with better patch titles, please let me know. I will fix them up locally. -- Best Regards Masahiro Yamada
