The swp and spwb instructions were deprecated in ARMv6. ARMv8 obsoleted the instruction. Despite this, many applications rely on these instruuctions. This patch starts with the version present in the arm architecture. However, it uses the ldx*()/stx*() functions to implement the handler in C code. It also removes a lot of code that is not needed.
