    sys/ia64/include     cpu.h 
  Log:
  Undo the mistake made in revision 1.77 of trap.c and which was the
  ultimate trigger for the follow-up fixes in revisions 1.78, 1.80,
  1.81 and 1.82 of trap.c. I was simply too pre-occupied with the
  gateway page and how it blurs kernel space with user space and
  vice versa that I couldn't see that it was all a load of bollocks.
  
  It's not the IP address that matters, it's the privilege level that
  counts. We never run in user space with lifted permissions and we
  sure can not run in kernel space without it. Sure, the gateway page
  is the exception, but not if you look at the privilege level. It's
  user space if you run with user permissions and kernel space otherwise.
  
  So, we're back to looking at the privilege level like it should be.
  There's no other way.
