Looks good.
Did this find any bugs, btw? We've had a few cases where we forgot to
use the proper user access function, and code just happened to work
because it all boils down to the same thing and never got any page
faults in practice anyway..
I'd obviously hope that we have caught all of them, but.. IOW, has
SMAP actually triggered for anybody in testing inside Intel?
