[PATCH 4/6] xen: export NUMA topology in physinfo hcall
This patch modifies the physinfo hcall to export NUMA CPU and Memory
topology information. The new physinfo hcall is integrated into libxc
and xend (xm info specifically). Included in this patch is a minor
tweak to xm-test''s xm info testcase. The new fields in xm info are:
nr_nodes : 4
mem_chunks : node0:0x0000000000000000-0x0000000190000000
