This patch adds support for AMD's new extended topology.
If processor supports CPUID 80000026 leaf then obtain
the topology information using new method.
Algorithm:
if CPUID is AMD:
then
check for AMD's extended cpu tology leaf.
if yes
then extract cpu tology based on
AMD programmer manual's instruction.
else
then fallback to existing topology function.
endif
endif
