     from *u_ar0.  The other is that u_ar0 is sometimes an absolute address
     in kernel memory, and on other systems it is an offset from the beginning
     of the `struct user'.
     
     As a practical matter, we don't know where the registers actually are,
     so we have to pass the whole area to GDB.  We encode the value of u_ar0
     by setting the .regs section up so that its virtual memory address
     0 is at the place pointed to by u_ar0 (by setting the vma of the start
     of the section to -u_ar0).  GDB uses this info to locate the regs,
