It may be better to move the generic __v7_setup here and have a specific
entry for ARM Ltd cores (mask 0xff0f0000 and value 0x410f0000).
In general, I would have liked a different way (still ID-based) of
handling such issues without duplicating the whole structure. But I see
this becoming the standard as proc-v6.S follows it as well.
