We can't just clear the user read permission in book3e pte, because
that will also clear supervisor read permission.  This surely isn't
desired.  Fix the problem by adding the supervisor read back.

For 2.6.34 stable commit 55052eeca6d71d76f7c3f156c0501814d8e5e6d3

Wondering what happened to this patch (and 2 other) getting into stable queue for .34.x

They are still in the "to-apply" queue.  Please be patient, I was busy
with the .35-rc1 merge window and now am catching up on the stable
trees.  There's over 130 patches that people seem to want in the first
.34 stable release, so it's taking some time to get them all in and
tested.

thanks,
