Unfortunately, it isn't.  CPU identification has become a fairly murky
business on ARM that the information exported from /proc/cpuinfo can
no longer precisely identify the CPU itself.

For example, we just treat Cortex A8 and A9 as "ARMv7" because from the
kernel's point of view, they're the same.
