Jianguo Wu 7cd10a60c3 [IA64] Fix a node distance bug
In arch ia64, has following definition:
extern u8 numa_slit[MAX_NUMNODES * MAX_NUMNODES];
#define node_distance(from,to) (numa_slit[(from) * num_online_nodes() + (to)])

num_online_nodes() is a variable value, it can be changed after hot-remove/add
a node.

In my practice, I found node distance is wrong after offline
a node in IA64 platform. For example system has 4 nodes:
node distances:
node   0   1   2   3
  0:  10  21  21  32
  1:  21  10  32  21
  2:  21  32  10  21
  3:  32  21  21  10

linux-drf:/sys/devices/system/node/node0 # cat distance
10  21  21  32
linux-drf:/sys/devices/system/node/node1 # cat distance
21  10  32  21

After offline node2:
linux-drf:/sys/devices/system/node/node0 # cat distance
10 21 32
linux-drf:/sys/devices/system/node/node1 # cat distance
32 21 32	--------->expected value is: 21  10  21
