#     powerpc: module_[32|64].c: replace swap function with built-in one
#     
#     Replace relaswap with built-in one, because relaswap
#     does a simple byte to byte swap.
#     
#     Since Spectre mitigations have made indirect function calls more
#     expensive, and the default simple byte copies swap is implemented
#     without them, an "optimized" custom swap function is now
#     a waste of time as well as code.
