Subject: [patch 67/69] CPUFREQ: Correct revision mask for powernow-k8

-stable review patch. If anyone has any objections, please let us know.
---------------------

From: Dave Jones <[email protected]>

Mark Langsdorf points out that the correct define for this
revision bump is 0x80000. Also to save us having to keep
renaming the #define, give it a more meaningful name.
