Kernel prints respective warnings about various EPOW events for user information/action after parsing EPOW interrupts. At times below EPOW reset event warning is seen to be flooding kernel log over a period of time. May 25 03:46:34 alp kernel: Non critical power or cooling issue cleared May 25 03:46:52 alp kernel: Non critical power or cooling issue cleared May 25 03:53:48 alp kernel: Non critical power or cooling issue cleared May 25 03:55:46 alp kernel: Non critical power or cooling issue cleared May 25 03:56:34 alp kernel: Non critical power or cooling issue cleared May 25 03:59:04 alp kernel: Non critical power or cooling issue cleared May 25 04:02:01 alp kernel: Non critical power or cooling issue cleared These EPOW reset events are spurious in nature and are triggered by firmware without an actual EPOW event being reset. This patch avoids these multiple EPOW reset warnings by using a counter variable. This variable is incremented every time an EPOW event is reported. Upon receiving a EPOW reset event the same variable is checked to filter out spurious events and decremented accordingly. This patch also improves log messages to better describe EPOW event being reported. Merged adjacent log messages into single one to reduce number of lines printed per event.
