Comment 13 for bug 1427995

Verified this on a fully-enabled POWER8 system; confirming that without the patch, multiple CPUs show incorrect node values (random garbage):

144,18,3,0,,18,18,18,18
145,18,3,0,,18,18,18,18
146,18,3,436483456,,18,18,18,18
147,18,3,256,,18,18,18,18
148,18,3,436482464,,18,18,18,18
149,18,3,256,,18,18,18,18

158,19,3,33,,19,19,19,19
159,19,3,0,,19,19,19,19

... And with the patch, things are the way they should:
