Marc,

I would like to route this through Paolo's tree/queue for 6.2 along with
a big pile of other selftests updates.  I am hoping to get the selftests
pile queued sooner than later as there is a lot of active development in
that area, and don't want to have the selftests be in a broken state.
I'm going to send Paolo a pull request shortly, I'll Cc you (and others)
to keep everyone in the loop and give a chance for objections.


Fix a typo and an imminenent not-technically-a-bug bug in the single-step
test where executing an atomic sequence in the guest with single-step
enable will hang the guest due to eret clearing the local exclusive
monitor.
