cpuctx->unique_pmu was originally introduced as a way to identify cpuctxs with shared pmus in order to avoid visiting the same cpuctx more than once in a for_each_pmu loop. cpuctx->unique_pmu == cpuctx->pmu in non-software task contexts since they have only one pmu per cpuctx. Since perf_pmu_sched_task() is only called in hw contexts, this patch replaces cpuctx->unique_pmu by cpuctx->pmu in it. The change above, together with the previous patch in this series, removed the remaining uses of cpuctx->unique_pmu, so we remove it altogether.

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.
