Sorry, forgot to add "-e FTRACE" to the steps above. Here it is:

	export ARCH=riscv CROSS_COMPILE=riscv32-linux-
	make distclean
	make defconfig
	make 32-bit.config
	./scripts/config \
		-e DEBUG_KERNEL \
		-e DEBUG_INFO \
		-e DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT \
		-d DEBUG_INFO_NONE \
		-d DEBUG_INFO_REDUCED \
		-e FTRACE
	make olddefconfig
	make -j vmlinux

Everything else still applies.
