mainlining shenanigans
49ad31e9d7
If some part of the PCI topology is already configured (by the boot firmware) but not all, and it includes hotplug bridges, we may need to extend the bus resources of those bridges to accommodate any future hotplugs, in the same way we already do with the normal hotplug case. Pass the available buses to pci_scan_child_bus_extend() even when the bridge in question is already configured so the bus allocation code can use these available buses to extend the possible hotplug bridges below.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
