Wang Wensheng cacaeb0c23 powerpc/perf: Fix symbol undeclared warning
Build kernel with `C=2`:
arch/powerpc/perf/isa207-common.c:24:18: warning: symbol
'isa207_pmu_format_attr' was not declared. Should it be static?
arch/powerpc/perf/power9-pmu.c:101:5: warning: symbol 'p9_dd21_bl_ev'
was not declared. Should it be static?
arch/powerpc/perf/power9-pmu.c:115:5: warning: symbol 'p9_dd22_bl_ev'
was not declared. Should it be static?

Those symbols are used only in the files that define them so we declare
them as static to fix the warnings.

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.
