This patch adds user_atomic_cmpxchg_inatomic() to use CMPXCHG
instruction against a user space address.
This generalizes the already existing futex_atomic_cmpxchg_inatomic()
so it can be used in other contexts. This will be used in the
upcoming support for Intel MPX (Memory Protection Extensions.)
[ hpa: replaced #ifdef inside a macro with IS_ENABLED() ]
