This is a small cache which collects correctable memory errors per 4K
|
page PFN and counts their repeated occurrence. Once the counter for a
|
PFN overflows, we try to soft-offline that page as we take it to mean
|
that it has reached a relatively high error count and would probably
|
be best if we don't use it anymore.
|
|
Bear in mind that this is absolutely useless if your platform doesn't
|
have ECC DIMMs and doesn't have DRAM ECC checking enabled in the BIOS.
