VCPU Dispatch Statistics
========================
For Shared Processor LPARs, the POWER Hypervisor maintains a relatively
static mapping of the LPAR processors (vcpus) to physical processor

a vcpu as represented by the first field, followed by 8 numbers.
The first number corresponds to:
1. total vcpu dispatches since the beginning of statistics collection
The next 4 numbers represent vcpu dispatch dispersions:
2. number of times this vcpu was dispatched on the same processor as last
time
3. number of times this vcpu was dispatched on a different processor core
as last time, but within the same chip
4. number of times this vcpu was dispatched on a different chip
5. number of times this vcpu was dispatches on a different socket/drawer
(next numa boundary)
(next numa boundary)
The final 3 numbers represent statistics in relation to the home node of
the vcpu:
6. number of times this vcpu was dispatched in its home node (chip)
7. number of times this vcpu was dispatched in a different node
8. number of times this vcpu was dispatched in a node further away (numa
