It seems that POWER10 was renamed to Power10 but not POWER9. And :

   https://en.wikipedia.org/wiki/Power9  redirects to POWER9
   https://en.wikipedia.org/wiki/POWER10 redirects to Power10

I will keep the upper case POWER9. No need to resend.

Thanks,

Ok. Thanks! I'll keep this nomenclature on the pseries documentation
patches as well.
