There are three symbols (two variables and a function) that are being used solely in the same file (imc-pmu.c), thus, these symbols should be static, but they are not. This was detected by sparse: arch/powerpc/perf/imc-pmu.c:31:20: warning: symbol 'nest_imc_refc' was not declared. Should it be static? arch/powerpc/perf/imc-pmu.c:37:20: warning: symbol 'core_imc_refc' was not declared. Should it be static? arch/powerpc/perf/imc-pmu.c:46:16: warning: symbol 'imc_event_to_pmu' was not declared. Should it be static? This patch simply adds the 'static' storage-class definition to these symbols, thus, restricting their usage only in the imc-pmu.c file.

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.
