…ternatives Under FTRACE=y, DYNAMIC_FTRACE=n, and RISCV_ALTERNATIVE_EARLY=n, the kernel panics upon returning from _mcount() in the early boot path. This occurs during _start_kernel() -> setup_vm() -> apply_early_boot_alternatives(). The CC_FLAGS_FTRACE is only removed from alternative.c when CONFIG_RISCV_ALTERNATIVE_EARLY=y. Therefore, no function calls should be made to alternative.c during early boot in this configuration.
