I cannot
Implement generic UP cmpxchg() where an arch doesn't otherwise support it.
This assuming that the arch doesn't have support SMP without providing its own
cmpxchg() implementation.
This is required because cmpxchg() is used by the reduced work queue patches to
adjust the management data in a
