| 8 | * There are a number of reasons for patching instructions. Rather than duplicating code |
| 9 | * all over the place, we put the common stuff here. Reasons for patching: in-kernel |
| 10 | * module-loader, virtual-to-physical patch-list, McKinley Errata 9 workaround, and gate |
| 11 | * shared library. Undoubtedly, some of these reasons will disappear and others will |
| 12 | * be added over time. |
