Hi Changbin,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on linus/master]
[also build test WARNING on v4.17 next-20180605]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url: https://github.com/0day-ci/linux/commits/changbin-du-intel-com/kernel-hacking-GCC-optimization-for-better-debug-experience-Og/20180606-001415
config: sparc64-allyesconfig (attached as .config)
compiler: sparc64-linux-gnu-gcc (Debian 7.2.0-11) 7.2.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
make.cross ARCH=sparc64

All warnings (new ones prefixed by >>):

>> WARNING: vmlinux.o(.text.unlikely+0x1fc): Section mismatch in reference from the function init_tick_ops() to the function .init.text:get_tick_patch()
The function init_tick_ops() references
the function __init get_tick_patch().
This is often because init_tick_ops lacks a __init
annotation or the annotation of get_tick_patch is wrong.
