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

[Juergen Gross <juergen.gross@xxxxxxxxxxxxxx>]

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.
