Unfortunately this breaks the build - see https://patchwork.ozlabs.org/project/linuxppc-dev/patch/1613808853-78381-1-git-send-email-yang....@linux.alibaba.com/ This is because 'boot/mktree.c' is a userspace program without access to the usual kernel headers. It might be best to get coccicheck to exclude all of 'arch/powerpc/boot/' as I believe everything in that directory is compiled differently to the rest of the kernel (see the Makefile), but maybe just blacklisting boot/mktree.c would be sufficient.
