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