Previously we distributed spare resources only upon hot-add, so if the initial root bus scan found devices that had not been fully configured by the BIOS, we allocated only enough resources to cover what was then present. If some of those devices were hotplug bridges, we did not leave any additional resource space for future expansion. Distribute the available resources for root buses, too, to make this work the same way as the normal hotplug case.

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.
