-/* makecontext sets up a stack and the registers for the
-   user context.  The stack looks like this:
-
-               +-----------------------+
-	       | padding as required   |
-               +-----------------------+
-    sp ->      | parameter 7-n         |
-               +-----------------------+
-
-   The registers are set up like this:
-     %x0 .. %x7: parameter 1 to 8
-     %x19   : uc_link
-     %sp    : stack pointer.
