    locking/atomics, cmpxchg: Privatize the inclusion of asm/cmpxchg.h · 84567995

    After commit:
      654672d4 ("locking/atomics: Add _{acquire|release|relaxed}() variants of some atomic operations")
    Architectures may only provide {cmp,}xchg_relaxed definitions in
    asm/cmpxchg.h. Other variants, such as {cmp,}xchg, may be built in
    linux/atomic.h, which means simply including asm/cmpxchg.h may not get
    the definitions of all the{cmp,}xchg variants.
    Therefore, we should privatize the inclusions of asm/cmpxchg.h to
    keep it only included in arch/* and replace the inclusions outside
    with linux/atomic.h
