Subject: [PATCH 0/6] jailhouse: Enhance secondary Jailhouse guest support /wrt PCI

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
 - MMCONFIG support for x86 guests

As most changes affect x86, I would suggest to route the series also via
tip after the necessary acks are collected.
