For log-dirty operations a 64-bit field is being truncated to become an "int" return value. Seeing the large number of arguments the present function takes, reduce its set of parameters to that needed for all operations not involving the log-dirty bitmap, while introducing a new wrapper for the log-dirty bitmap operations. This new function in turn doesn't need an "mb" parameter, but has a 64-bit return type. (Using the return value in favor of a pointer-type parameter is left as is, to disturb callers as little as possible.) While altering xc_shadow_control() anyway, also adjust the types of the last two of the remaining parameters.
