+ *  This include file sets up everything we need to access the load average
+ *  values in the kernel in a machine independent way.  First, it sets the
+ *  typedef "load_avg" to be either double or long (depending on what is
+ *  needed), then it defines these macros appropriately:
+ *
+ *	loaddouble(la) - convert load_avg to double.
+ *	intload(i)     - convert integer to load_avg.

+ * We assume that if FSCALE is defined, then avenrun and ccpu are type long.
+ * If your machine is an exception (mips, perhaps?) then make adjustments
+ * here.

+ * Defined types:  load_avg for load averages, pctcpu for cpu percentages.
