Integrity critical data may belong to a single subsystem or it may

to group or limit the data based on certain label. Limiting and
grouping critical data based on a label would make it flexible and
configurable to measure.
Define "label:=", a new IMA policy condition, for the IMA func
CRITICAL_DATA to allow grouping and limiting measurement of integrity
critical data.
Limit the measurement to the labels that are specified in the IMA
policy - CRITICAL_DATA+"label:=". If "label:=" is not provided with
the func CRITICAL_DATA, measure all the input integrity critical data.
