Bisection points to the above commit ("riscv: kexec: Fixup crash_smp_send_stop without multi cores"). Reverting it makes the build pass.
In order to reproduce: # See https://docs.tuxmake.org/ for complete documentation. # Original tuxmake command with fragments listed below. tuxmake --runtime podman --target-arch riscv --toolchain gcc-11 --kconfig defconfig
