Hi Paolo,
Here's the latest set of fixes for 5.9. The first patch is pretty
nasty, as a guest hitting this bug will have its vcpu stuck on a
fault, without any hope of it being resolved. Embarrassing, and
definitely a stable candidate. The second patch is only a cleanup
after the first one.
Please pull,
M.
