Basic x86 support [1] for running Linux as secondary Jailhouse [2] guest is currently pending in the tip tree. This builds on top and enhances the PCI support for x86 and also ARM guests (ARM[64] does not require platform patches and works already). Key elements of this series are: - detection of Jailhouse via device tree hypervisor node - function-level PCI scan if Jailhouse is detected -

...ntly leading us to return bogus ior -> head assignments through nvif, which causes WARN_ON(). So - fix this by verifying that we actually know that there's a head assigned to an ior before allowing it to be inherited through nvif. This -should- hopefully fix the WARN_ON on GT218 reported by Borislav.
