Hi Kefeng,
It's probably a bug fix that unveils the link errors.
tree: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git linux-5.4.y

config: riscv-allyesconfig (attached as .config)
compiler: riscv64-linux-gcc (GCC) 9.3.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross

# save the attached .config to linux build tree
COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-9.3.0 make.cross ARCH=riscv
If you fix the issue, kindly add following tag as appropriate

thanks for the input, we will check this false positive. Sorry for
the noise.

But this patch seems to cause issues:
https://lore.kernel.org/r/80234d43-3848-45e8-6d70-1db94129e35f(a)roeck-us.net
so I'll go drop it now.
