Of course, with a seperated architecture the arm64 code will be clear and
simple. when it merged with arm a few file should be duplicated with the name
"_v8" appended and many macro switch should be added. but most of the code will
be in armv8 directory which paralleled with armv7. it seems that this
implementation are more nice.
