compile_commands.json can be used with clangd to enable language server protocol-based assistance. For kernel itself this can be built with scripts/gen_compile_commands.py, but other projects (e.g., libbpf, or BPF selftests) can benefit from their own compilation database file, which can be generated successfully using external tools, like bear [0]. So, instead of adding compile_commands.json to .gitignore in respective individual projects, let's just ignore it globally anywhere in Linux repo. While at it, remove exactly such a local .gitignore rule under tools/power/cpupower.

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.
