+ * Name: syscall_clock_systimer
+ *
+ * Description:
+ *   In the kernel build, proxying for clock_systimer() must be handled
+ *   specially.  In the kernel phase of the build, clock_systimer() is
+ *   macro that simply accesses a global variable.  In the user phase of
+ *   the kernel build, clock_systimer() is a proxy function.
+ *
+ *   In order to fill out the table g_funclookup[], this function will stand
+ *   in during the kernel phase of the build so that clock_systemer() will
+ *   have an address that can be included in the g_funclookup[] table.
