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.
