Incorrect vCPU numbering

Hi All,

Currently experiencing more-so a visual issue when typing psrinfo, mpstat commands, as the virtual processors start from 8-39, as below:

# psrinfo -pv
The physical processor has 32 virtual processors (8-39)
  UltraSPARC-T2 (chipid 0, clock 1165 MHz)

Can't seem to find anything to explain why this might be, and why doesn't it range from (0-31) instead?

Any help would be appreciated.

Cheers,
