fresh patch for review?


Yes, I think I'll have some time this week to do this.
Sorry for the delay...

Subject: [Xen-devel] [PATCH] use per-cpu variables in cpufreq

The cpufreq driver used some local arrays indexed by cpu
number. This patch
replaces those arrays by per-cpu variables. The AMD and INTEL
specific parts
used different per-cpu data structures with nearly identical
semantics.
Fold the two structures into one by adding a generic
architecture data item.
