+         Some architectures require 64 bit accesses to be 64 bit
+         aligned, which also requires structs containing 64 bit values
+         to be 64 bit aligned too. This includes some 32 bit
+         architectures which can do 64 bit accesses, as well as 64 bit
+         architectures without unaligned access.
+
+         This symbol should be selected by an architecture if 64 bit
+         accesses are required to be 64 bit aligned in this way even
+         though it is not a 64 bit architecture.
+
+         See Documentation/unaligned-memory-access.txt for more
+         information on the topic of unaligned memory accesses.
