    acpi_cpu: do not apply P_LVLx_LAT rules to latencies returned by _CST
    
    ACPI specification states that if P_LVL2_LAT >100, then a system
    doesn't support C2; if P_LVL3_LAT >1000, then C3 is not supported.
    
    But there are no such rules for Cx state data returned by _CST. If a
    state is not supported it should not be included into the return
    package. In other words, any latency value returned by _CST is valid,
    it's up to the OS and/or user to decide whether to use it.
