The new pseries-4.0 machine type defaults to enabling Spectre/Meltdown mitigations. Unfortunately those mitigations aren't implemented for TCG because we're not yet sure if they're necessary or how to implement them. We don't fail fatally, but we do warn in this case, because it is quite plausible that Spectre/Meltdown can be exploited through TCG (at least for the guest to get access to the qemu address space). This create noise in our testcases though. So, modify the affected tests to explicitly disable the mitigations to suppress these warnings. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
