Kajol Jain 60bd7936f9 powerpc/hv-24x7: Fix pvr check when setting interface version 
Commit ec3eb9d941 ("powerpc/perf: Use PVR rather than
oprofile field to determine CPU version") added usage
of pvr value instead of oprofile field to determine the
platform. In hv-24x7 pmu driver code, pvr check uses PVR_POWER8
when assigning the interface version for power8 platform.
But power8 can also have other pvr values like PVR_POWER8E and
PVR_POWER8NVL. Hence the interface version won't be set
properly incase of PVR_POWER8E and PVR_POWER8NVL.
Fix this issue by adding the checks for PVR_POWER8E and
PVR_POWER8NVL as well.

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.
