This patch should apply cleanly to the 2.6.23-git7 kernel. It changes the powernow-k8 driver code that deals with 3rd generation Opteron, Phenom, and later processors to match the architectural pstate driver described in the AMD64 Architecture Programmer's Manual Volume 2 Chapter 18. The initial implementation of the hardware pstate driver for PowerNow! used some processor-version specific features, and would not be maintainable in the long term as the processor features changed. This architectural driver should work on all future AMD processors.

This reverts commit aeeddc14, which was half-baked and broken. It just resulted in compile errors, since cpufreq_register_driver() still changes the 'driver_data' by setting bits in the flags field. So claiming it is 'const' _really_ doesn't work. Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

When we stop allocating percpu memory for not-possible CPUs we must not touch the percpu data for not-possible CPUs at all. The correct way of doing this is to test cpu_possible() or to use for_each_cpu(). This patch is a kernel-wide sweep of all instances of NR_CPUS. I found very few instances of this bug, if any. But the patch converts lots of open-coded test to use the preferred helper macros.

powernow-k8: Let cpufreq driver handle affected CPUs Let the cpufreq driver manage AMD Dual-Core CPUs being tied together. Since cpufreq driver's affected CPUs data, cpufreq_policy->cpus, already knows about which cores are tied together, powernow driver does not have keep its internal data for every core. (even a pointer.. it will never be called on) Telling cpufreq driver about cpu_core_map at init time is sufficient.
