Bodo Stroesser 51a6b0c59a [PATCH] uml: s390 preparation, sighandler interface abstraction
s390 passes parameters in registers.  So the only safe way to find out the
address of signal context, error-address and error-type (trap_no), which are
passed to signal handlers as parameters, is to declare these parameters.

So I inserted an subarch-specific macro which holds the declaration of
parameters for signal handlers.
