22b5de86a5 add mpu_stack_guard pseudomodule (just Cortex-M for now) 
triggers an exception during stack overflow,
but at a cost of 32-63 bytes of RAM per thread.

9ad9f400e6 cpu/cortexm_common: Remove register keyword from variables 
register is deprecated when building C++11 code and removed in C++17,
using it will cause build failures with C++ and -Werror. The register
hint keyword is likely ignored in GCC anyway.
