[PATCH v2 02/22] [SCSI] mpt2sas, mpt3sas: Added support to log message when Temperature Threshold exceeds for any Sensor

From: Sreekanth Reddy
Date: Mon Jan 12 2015 - 01:09:57 EST

This patch will log a message when driver receives "Temperature Threshold exceeded" event from any temperature sensor.

The message will look similar to like
mpt3sas0: Temperature Threshold flags a b c d exceeded for Sensor: x !!!
mpt3sas0: Current Temp In Celsius: y

where a b c d are threshold flags 0 1 2 3

Change_set:
1. Get the number of sensor count of this IOC by reading IO Unit page 8 at driver initialization time.
2. Also unmask the Temperature Threshold Event at driver initialization time,
3. Whenever a MPI2_EVENT_TEMP_THRESHOLD event is received from the firmware then print the sensor number, the maximum threshold number it has exceed and the current temperature of this sensor.
