| ---help--- | |
| 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. |
