    Subject[PATCH v5 0/7] jailhouse: Enhance secondary Jailhouse guest support /wrt PCI
    Date
    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 v5:
    - fix build breakage of patch 6 on i386

    Changes in v4:
    - slit up Kconfig changes
    - respect pcibios_last_bus during mmconfig setup
    - cosmetic changes requested by Andy

    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
