    [PATCH] acpi bridge hotadd: ACPI based root bridge hot-add · c431ada4
    Rajesh Shah 提交于
    When you hot-plug a (root) bridge hierarchy, it may have p2p bridges and
    devices attached to it that have not been configured by firmware.  In this
    case, we need to configure the devices before starting them.  This patch
    separates device start from device scan so that we can introduce the
    configuration step in the middle.
    
    I kept the existing semantics for pci_scan_bus() since there are a huge number
    of callers to that function.
    
    Also, I have no way of testing the changes I made to the parisc files, so this
    needs review by those folks.  Sorry for the massive cross-post, this touches
    files in many different places.
