Changes

 The problem can happen during or after running ldm set-vcpu in control domain.

Cause

Due to bug BUG 15756136, this issue can happen on M10-4S and T4-1 servers running Solaris 11.1

This is due to mismatch in cpu_coreid of cpu_physid_t versus cpu_core in machcpu.

The output of these 2 list should match each other.
