   From: Kevin Buettner <kevinb@redhat.com>

   The patch below should be non-controversial.  It merely adds the
   TARGET_ADJUST_BREAKPOINT_ADDRESS method.  Code which uses it (the
   possibly controversial bit) will come in patch #3.  Documentation will
   be in the next patch, #2.  Finally, target specific code which
   requires TARGET_ADJUST_BREAKPOINT_ADDRESS will be posted in patch #4.

Do we really need the "TARGET" in the name of the new method?  It made
me think that this was something that was going to be added to the
target-vector instead of the architecture vector.
