RAS/CEC: Reduce offline page threshold for Intel systems
A large scale study of memory errors on Intel systems in data centers
showed that aggressively taking pages with corrected errors offline is
the best strategy of using corrected errors as a predictor of future
uncorrected errors.
Set the threshold to "2" on Intel systems. AMD guidance is that this is
not necessary for their systems.
