SVN rev 208507 on 2010-05-24 15:45:05Z by jhb
Add support for corrected machine check interrupts. CMCI is a new local
APIC interrupt that fires when a threshold of corrected machine check
events is reached. CMCI also includes a count of events when reporting
corrected errors in the bank's status register. Note that individual
banks may or may not support CMCI. If they do, each bank includes its own
threshold register that determines when the interrupt fires. Currently
the code uses a very simple strategy where it doubles the threshold on
each interrupt until it succeeds in throttling the interrupt to occur
only once a minute (this interval can be tuned via sysctl). The threshold
is also adjusted on each hourly poll which will lower the threshold once
events stop occurring.
