[ Upstream commit4b53a3c721] When OCXL is enabled and HOTPLUG_PCI is disabled, it results in the following Kbuild warning: WARNING: unmet direct dependencies detected for HOTPLUG_PCI_POWERNV Depends on [n]: PCI [=y] && HOTPLUG_PCI [=n] && PPC_POWERNV [=y] && EEH [=y] Selected by [y]: - OCXL [=y] && PPC_POWERNV [=y] && PCI [=y] && EEH [=y] The reason is that OCXL selects HOTPLUG_PCI_POWERNV without depending on or selecting HOTPLUG_PCI while HOTPLUG_PCI_POWERNV is subordinate to HOTPLUG_PCI. HOTPLUG_PCI_POWERNV is a visible symbol with a set of dependencies. Selecting it will lead to overlooking its other dependencies as well. Let OCXL depend on HOTPLUG_PCI_POWERNV instead to avoid Kbuild issues.

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.
