We used to generate different helpers for local and full
{cmp,}xchg(); these days the barriers are in arch_{cmp,}xchg()
instead and generated helpers are identical for local and
full cases. No need for those parametrized includes of
asm/xchg.h - we might as well insert its contents directly
in asm/cmpxchg.h and do it only once.
