The most common error with powernow-k8 is an ACPI _PSS error caused either by failure to load the ACPI processor module or a bad parse of the _PSS object. Make the error message returned to the user in these situations more straightforward and easier to understand. -Mark Langsdorf Operating System Research Center AMD Signed-off-by: NMark Langsdorf <mark.langsdorf@amd.com> Signed-off-by: NAndreas Herrmann <andreas.herrmann3@amd.com> Signed-off-by: NDave Jones <davej@redhat.com>

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 is from an earlier message from 'Christoph Lameter': cpu_core_map is currently an array defined using NR_CPUS. This means that we overallocate since we will rarely really use maximum configured cpu. If we put the cpu_core_map into the per cpu area then it will be allocated for each processor as it comes online. This means that the core map cannot be accessed until the per cpu area has been allocated. Xen does a weird thing here looping over all processors and zeroing the masks that are not yet allocated and that will be zeroed when they are allocated. I commented the code out.

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.
