We are currently doing the timing for debug purposes of the P9 entry path using the accumulators and terminology defined by the old entry path for P8 machines. Not only the "real-mode" and "napping" mentions are out of place for the P9 Radix entry path but also we cannot change them because the timing code is coupled to the structures defined in struct kvm_vcpu_arch. Add a new CONFIG_KVM_BOOK3S_HV_P9_TIMING to enable the timing code for the P9 entry path. For now, just add the new CONFIG and duplicate the structures. A subsequent patch will add the P9 changes.

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.
