Let's take percpu.h as an example. We need to include it in <rtems/score/thread.h> -- the main header for thread scheduling that is included by virtually every source file in the supercore. We can't include the CPU-dependent headers here, unless we use the CPP #if-elif cascase as mentioned by Sebastian.
