[ Upstream commit 2a76352ad2cc6b78e58f737714879cc860903802 ] Currently we add individual copy of same OPP table for each CPU within the cluster. This is redundant and doesn't reflect the reality. We can't use core cpumask to set policy->cpus in ve_spc_cpufreq_init() anymore as it gets called via cpuhp_cpufreq_online()->cpufreq_online() ->cpufreq_driver->init() and the cpumask gets updated upon CPU hotplug operations. It also may cause issues when the vexpress_spc_cpufreq driver is built as a module. Since ve_spc_clk_init is built-in device initcall, we should be able to use the same topology_core_cpumask to set the opp sharing cpumask via dev_pm_opp_set_sharing_cpus and use the same later in the driver via dev_pm_opp_get_sharing_cpus.

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.
