intel_pstate_hwp_set() is the only function walking policy->cpus in intel_pstate. The rest of the code simply assumes one CPU per policy, including the initialization code. Therefore it doesn't make sense for intel_pstate_hwp_set() to walk policy->cpus as it is guaranteed to have only one bit set for policy->cpu. For this reason, rearrange intel_pstate_hwp_set() to take the CPU number as the argument and drop the loop over policy->cpus from it. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> |

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.
