This is an attempt at a more correct solution to the patch sent
earlier "kallsyms: fix absolute addresses for kASLR".
The main problem is that the entire per_cpu area needs to be treated
as absolute by kallsyms. This series adds the logic to recognize the
per_cpu memory range and treat it as absolute in the kallsyms tool.
