atomicity.h: Replace '__ATOMICITY_INLINE' with 'inline'. 

2000-11-27  Franz Sirl  <Franz.Sirl-kernel@lauterbach.com>

        * config/cpu/powerpc/bits/atomicity.h: Replace '__ATOMICITY_INLINE'
        with 'inline'.
        (__ex__atomic_add): Add __volatile__ to asm.
        (__atomic_add): Likewise.
        (__compare_and_swap): Likewise.
        (__always_swap): Likewise.
        (__test_and_set): Likewise.
