Keeping everything strictly linear is quite cumbersome, why not let the compiler do this for you? enum kvm_sysreg_id { MPIDR_EL1 = 1, ... NR_SYS_REGS } That way gcc automatically counts the IDs up for you. You eliminate a potential source of breakage (duplicate IDs) and the code is even easier to read ;).
