Most likely, I'm using 9.2 from crosstool:

x86_64-linux-gcc (GCC) 9.2.0

crosstool is a handy way to install GCC for kernel compilations, here
are my notes:

listings: https://www.kernel.org/pub/tools/crosstool/

wget https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/8.1.0/x86_64-gcc-8.1.0-nolibc-x86_64-linux.tar.xz
pushd /opt/cross/
tar -xf ~/tmp/crosstool/x86_64-gcc-8.1.0-nolibc-x86_64-linux.tar.xz

In top level create GNUMakefile:

CROSS_COMPILE=/opt/cross/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-
include Makefile
