+config HAVE_EFFICIENT_UNALIGNED_ACCESS

+       help
+         Some architectures are unable to perform unaligned accesses
+         without the use of get_unaligned/put_unaligned. Others are
+         unable to perform such accesses efficiently (e.g. trap on
+         unaligned access and require fixing it up in the exception
+         handler.)
+
+         This symbol should be selected by an architecture if it can
+         perform unaligned accesses efficiently to allow different
+         code paths to be selected for these cases. Some network
+         drivers, for example, could opt to not fix up alignment
+         problems with received packets if doing so would not help
+         much.
+
+         See Documentation/unaligned-memory-access.txt for more
+         information on the topic of unaligned memory accesses.
