+Subject: [PATCH] Endianness macros should not dereference unaligned pointers
+
+The LE_*/BE_* macros previously worked by casting the pointer passed to them to a pointer to the correct integer type, then dereferencing it. This will not work on architectures which don't allow unaligned data access. Instead, access one byte at a time and shift to form the value.
