powernow-k8: reorder the PST table to match the ACPI table
PATCH 1/1 powernow-k8: reorder the PST table to match the ACPI table
The PST code in powernow-k8 orders pstate entries in the opposite order from the ACPI code. This can confuse some userspace tools. Get both codes to order pstates in the same way.
