Thread-topic:	Testing the NUMA patches on the Unisys ES7000

All,

I tested out Ryan Harper's latest NUMA patches on our ES7000s.

I was able to bring up a 4-cell, 32-way machine with 64 GB of memory and run multiple guests on them.

Here's the NUMA info and the heap info that I generated on the serial console.

Thanks

Raj
