[PATCH] x86: Refactor thermal throttle processing
Refactor the event processing (syslog messaging and rate limiting) into separate file therm_throt.c. This allows consistent reporting of CPU thermal throttle events. After ACK'ing the interrupt, if the event is current, the user (p4.c/mce_intel.c) calls therm_throt_process to log (and rate limit) the event. If that function returns 1, the user has the option to log things further (such as to mce_log in x86_64).
