Thanks a lot for exploring more CPU variants which share the same data
source packet format.

The latest Linux kernel have defined the CPU part number and MIDR for
below CPU variants:

- A78
- X1
- A715
- A78C

I would like to use a patch to support these CPUs in perf tool.  Given
other CPU variants (X3/V2/A720) have not been supported in the kernel,
and so far no one requests them, I would like leave them out.

Please let me know if this okay for you or not.
