commit 18b756a7e525e4bd6cd2aa8de86e4a48a583366a
Author:     Warner Losh <imp@FreeBSD.org>

    atomic_fcmpset* return int, not the type of *.
    
    fcmpset returns true/false as a int, so make the return types and
    variables match the int to be consistent with other arch.
    
    (cherry picked from commit 2fb9d3808a3a0a8939502600cde69b04550d1e7d)
