Currently a topic subdirectory is supported in the pmu-events dir, in the following sample structure: /arch/platform/subtopic/mysubtopic.json Upto 256 levels of topic subdirectories are supported. So this means that JSONs may be located in a topic dir as well as the platform dir. This topic subdirectory causes problems if we want to add support for a vendor dir in the pmu-events structure (in the form arch/platform/vendor), in that we cannot differentiate between a vendor dir and a topic dir. Since the topic dir feature is not used, drop it so it does not block adding vendor subdirectory support.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
