      x86: create asm/cmpxchg.h · a436ed9c
      Jeff Dike authored
      i386:
      
        Rearrange the cmpxchg code to allow atomic.h to get it without needing to
        include system.h.  This kills warnings in the UML build from atomic.h about
        implicit declarations of cmpxchg symbols.  The i386 build presumably isn't
        seeing this because a separate inclusion of system.h is covering it over.
      
        The cmpxchg stuff is moved to asm-i386/cmpxchg.h, with an include left in
        system.h for the benefit of generic code which expects cmpxchg there.
      
        Meanwhile, atomic.h includes cmpxchg.h.
      
        This causes no noticable damage to the i386 build.
      
      x86_64:
      
        Move cmpxchg into its own header.  atomic.h already included system.h, so
        this is changed to include cmpxchg.h.
      
        This is purely cleanup - it's not fixing any warnings - so if the x86_64
        system.h isn't considered as cleanup-worthy as i386, then this can be
        dropped.
      
        It causes no noticable damage to the x86_64 build.
      
      uml:
      
        The i386 and x86_64 cmpxchg patches require an asm-um/cmpxchg.h for the
        UML build.
