+   These are little snippets of code in intr-stubs.S, one for
+   each of the 256 possible x86 interrupts.  Each one does a
+   little bit of stack manipulation, then jumps to intr_entry().
+   See intr-stubs.S for more information.
+
+   This array points to each of the interrupt stub entry points
+   so that intr_init() can easily find them. */
