5 | This is a small cache which collects correctable memory errors per 4K | |
6 | page PFN and counts their repeated occurrence. Once the counter for a | |
7 | PFN overflows, we try to soft-offline that page as we take it to mean | |
8 | that it has reached a relatively high error count and would probably | |
9 | be best if we don't use it anymore. | |
