When hardware coordination is in use, the contents\nof this file appear the same as when no coordination is required. This can\nlead to some confusion among user-space programs, for example, that do not\nknow that extra coordination is required to force a CPU core to a particular\nspeed to control power consumption.\n\nTo fix this, create a \"related_cpus\" attribute that always displays the\ncoordination map regardless of whatever coordination strategy the cpufreq\ndriver uses (sw or hw). If the cpufreq driver does not provide a value, fall\nback to policy-\u003ecpus.\n\nSigned-off-by: Darrick J.

__cpufreq_set_policy\n2. governer methods (.governer) must NOT take the lock_cpu_hotplug()\n lock in any way; they are called with the lock taken already\n3. if your governer spawns a thread that does

gets written by all the CPUs. So,\nthe frequency set by last CPU will be seen on /proc/cpuinfo of all the\nCPUs in the system. What you see also depends on whether you have constant_tsc\ncapable CPU or not.\n\nOn ia64:\nIt is always boot time frequency of a particular CPU that gets displayed.\n\nThe patch below changes this to:\nShow the last known frequency of the particular CPU, when cpufreq is present. If\ncpu doesnot support changing of frequency through cpufreq, then boot frequency\nwill be shown.

This reduces the number of indirect includes of sched.h\nby ~300. Another ~400 pointless direct includes can be removed after\nthis disentangling (patch to follow later).\nHowever, quite a few indirect includes need to be fixed up for this.\n\nIn order to feed the patches through -mm with as little disturbance as\npossible, I\u0027ve split out the fixes I accumulated up to now (complete for\ni386 and x86_64, more archs to follow later) and post them before the real\npatch.
