Hi Clark and John,
Cylictest's --smi option allows to continuously display SMIs that occur
during the measurement. However, the SMI count was not yet included in the
summary at the end of the program run. Added this.
While we are at it, update the list of Intel family 6 models that support
retrieving the SMI count by copying newly added items from kernel sources
at tools/power/x86/turbostat.
