With the inclusion of commit333f7b7686("powerpc/pseries: Implement indexed-count hotplug memory add") and commit753843471c("powerpc/pseries: Implement indexed-count hotplug memory remove"), we now have complete handling of the RTAS hotplug event format as described by PAPR via ACR "PAPR Changes for Hotplug RTAS Events". This capability is indicated by byte 6, bit 2 (5 in IBM numbering) of architecture option vector 5, and allows for greater control over cpu/memory/pci hot plug/unplug operations. Existing pseries kernels will utilize this capability based on the existence of the /event-sources/hot-plug-events DT property, so we only need to advertise it via CAS and do not need a corresponding FW_FEATURE_* value to test for.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
