perf test: Add mechanism for skipping attr tests on auxiliary vector values
This can be used to skip tests or provide different test values on different platforms. For example to run a test only where Arm SVE is present add this to the config section: auxv = auxv["AT_HWCAP"] & 0x200000 == 0x200000 The value is a freeform Python expression that is evaled in the context of a map called "auxv" that contains the decoded auxiliary vector.

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.
