When turning off the engines, and the pmu sampling, clear the previous value as the current measurement should be 0. v2: Use a for-loop v3: * Move clearing to timer self-dis-arm to avoid race with parking. * Clear frequency samples as well. v4: * Init frequency to idle_freq.

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.
