[PATCH v3 0/6] jailhouse: Enhance secondary Jailhouse guest support /wrt PCI

[Jan Kiszka]

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.

Changes in v3:
 - avoided duplicate scans of PCI functions under Jailhouse
 - reformated PCI_MMCONFIG condition and rephrase related commit log

Changes in v2:
 - adjusted commit log and include ordering in patch 2
 - rebased over Linus master
