Using 'hw_pressure' for local variable name is confusing in regard to the per-CPU 'hw_pressure' variable that uses the same name: include/linux/arch_topology.h:DECLARE_PER_CPU(unsigned long, hw_pressure); ... which puts it into a global scope for all code that includes <linux/topology.h>, shadowing the local variable. Rename it to avoid compiler confusion & Sparse 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 reStructuredText 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.
