temporary_table is a trivial copy of virtual_memory_regions, it isn't clear why it's needed. All the more that it's freely mixed with virtual_memory_regions itself. Also change a variable name to avoid confusion and improve indentation. Signed-off-by: Guennadi Liakhovetski <guennadi.liakhovetski@linux.intel.com>
