 * This internal header defines a data type used to hold interrupt-masking
 * information.  It is not formally specified whether this type is arithmetic
 * or non-arithmetic, and no portable uses for it have been defined.  It
 * exists in the common space for use by the kernel configuration mechanisms
 * included in the base system.

/*
 * If we are using interrupt masking to define our interrupt priority scheme,
 * then we need a type sufficient to hold a bitmask for at least 16 vectors
 * (for the IBM PC). Defining this as a long integer should be sufficient
