0942bf0ce0 make dkprintf() evaluate its parameters always 
Parameters of dkprintf() should be evaluated even if dkprintf() is
disabled.  Because this enables to find expression of parameter obsolete
and to avoid unnecessary compiler warnings such as "unused variable".

clone returns -EAGAIN when there is no vacant core.
In addition, clone tries to use the next vacant hyper-threading

of the next vacant physical core.
