Great.  Thanks for the fix, and thanks for testing.  Have you/can you also
test to be absolutely sure that users cannot access anything but the one
word from %gs, and that they cannot access >VM_MAX_ADDRESS using %ds
(i.e. normal accesses)?  I'm pretty darn sure that is all correct, but just
to be paranoid.


Thanks,
