Hi Sandipan Das,

   Thanks for your guidance. I will implement the Hygon L3 PMU support
on top of the Hygon uncore PMU driver (hygon_uncore.c) that is currently
under discussion on the list, rather than growing the Hygon bits further
inside the AMD uncore code. The goal is to finish the separation between
AMD and Hygon for uncore PMU drivers.
