   BTW, this might be a little confusing if you don't know the how the
HP systems handle proximity domains and NUMA.  This system is configured
for no node local memory.  Therefore all the memory is listed in
proximity domain 16.  This is a special node used to represent memory
interleaved from the other nodes.  The processors are on nodes 2 and 9,
which you can see is reflected in the lsapic eid value.  Decode below.
I'm a little concerned that changing ACPI static tables may end up
breaking references that exist in ACPI namespace.  Is that just my own
paranoia?  Thanks,

        Alex
