  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.
