as indicated upfront, and as now also confirmed by the large amount of
failures in the two most recent full unstable flights, our defaulting
to off of PV32 for non-shim Xen builds means in osstest PV32 needs to
be turned on again, or all the 32-bit PV Dom0 / DomU tests (and xtf
equivalents) would need to be disabled. This will eventually be needed
on all branches which we would backport this change to (I expect this
would be at least all fully maintained ones), and which have a PV32
setting (exists only as of 4.14).

As I don't expect disabling any tests is a reasonable course of action,
I think it's going to need to be the .config override. Could you please
arrange for this?
