Log:
  Expose doreti as a global symbol on amd64 and i386.
  
  doreti provides the common code path for returning from interrupt
  andlers on x86.  Exposing doreti as a global symbol allows kernel
  modules to include low-level interrupt handlers instead of requiring
  all low-level handlers to be statically compiled into the kernel.
