[PATCH 5/5] x86: Define atomic_compare_and_exchange_{val,bool}_acq using __atomic_compare_exchange_n

[Wilco Dijkstra]

Hi Adhemerval,

> Yeap, I am preparing a patchset to cleanup atomic.h/atomic-machine.h even more.

atomic-machine.h headers for almost all targets? Note there are another
5 patches besides these...
