Module Name:    src
Committed By:   pgoyette

Modified Files:
        src/sys/dev/acpi: acpi_tz.c

Log Message:
Change acpi_tz sensor behavior as follows:

1. ENVSYS_WARNOVER event is generated whenever any active cooling level
   is exceeded.

2. ENVSYS_CRITOVER event is generated whenever _HOT limit is exceeded;
   if the _HOT limit is not defined, then ENVSYS_CRITOVER will be
   generated when the _CRT limit is exceeded.

3. For Passive Cooling Only mode, there will be no change in behavior.

Additionally, since there are specific actions taken at each of the Active
Cooling Levels (powering parts of a zone on or off), and the limits are not
user-programmable,

4. The {warn,crit}{min,max} threshold levels will be specified only
   by the device itself;  event reporting thresholds may not be set
   from userland.

No comments received for two weeks after proposing these changes on both
current-users@ and tech-kern@
