	What are you actually trying to accomplish?  The values at
pin_obj_start are not magic numbers or instructions but user-friendly
values mapped at address 0.  It is trying to map values 0x0 and 0XBADFCA11
(bad function call) so that dereferencing a data pointer or a PowerOpen
ABI function pointer at address zero (0) will produce a visual clue.  This
is produced by assembly like:

       .long   0
       .long   0xBADFCA11

And you make the linker map label addr0 at physical address 0.
