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