In the v3 patchlog please also please describe to what extent new instructions are
enabled by the patch when run on real hardware (or on a simulator).

I.e. can user-space run those new instructions, while it couldn't before - or is
the patch purely for /proc/cpuinfo enumeration?

I.e. a comprehensive before/after comparison.

Thanks,

Ingo
