x86/numa: Store extra copy of numa_nodes_parsed
[ Upstream commit 48084cc153a5b0fbf0aa98d47670d3be0b9f64d5 ]
The topology setup code needs to know the total number of physical
nodes enumerated in SRAT; however NUMA_EMU can cause the existing
numa_nodes_parsed bitmap to be fictitious. Therefore, keep a copy of
the bitmap specifically to retain the physical node count.
