If a device is plugged in the pcie-root-port when VM kernel is booting, the kernel may wrongly disable the device. This bug was brought in by two patches of the linux kernel: https://patchwork.kernel.org/patch/10575355/ https://patchwork.kernel.org/patch/10766219/ VM runtime like kata uses this feature to boot microVM, so we must fix it up. We hack into the pcie native hotplug patch so that hotplug/unplug will work under this circumstance. Signed-off-by: Ying Fang <fangying1@huawei.com>
