Most architectures provide the cpu_logical_map[] definition as part of asm/smp.h, which is included by linux/smp.h. For irqchip drivers that work across a variety of platforms (MIPS, ARM, ARM64, etc.), and making use of cpu_logical_map[] this avoids making any architecture specific include in those drivers.
smp_plat.h uses -EINVAL, so make sure that header file include linux/errmo.h.
