Yes, using set_pte_at won't cure the race (which we *definitely* need to
investigate), but is actually a better choice than set_pte anyway -- it
will go x10 faster.

If only we had a 16 way machine on which we could try and reproduce this
problem :-)

The race is a big worry, but the code looks correct. Please can you tell
us more about the failure you observe. You mentioned that the shared
info page appears to be unmapped. Please provide more details.

Thanks,
Ian
