Hi guys,

I'm sending v2 of some of the patches at [1] in light of the discussions
at [2].

v2:
 - Patches 1-3 are trivial rebase on linux next 20201211, with conflicts
   fixed after eliminating what previously was "[PATCH 4/8] cppc_cpufreq:
   replace per-cpu structures with lists." Therefore, I have kept
   Viresh's acks.

 - Patch 4 is a merge between:
     - [PATCH 4/8] cppc_cpufreq: replace per-cpu structures with lists
     - [PATCH] cppc_cpufreq: optimise memory allocation for HW and NONE
       coordination
   both found at [1].

   This functionality was introducing the problem at [2] and it's fixed
   in this version by bailing out of driver registration if a _CPC entry
   is not found for a CPU.

   Yousaf, it would be great if you can test this and make sure it
   matches your expectations.

   Rafael, Viresh if you think this last patch introduces too many
   changes, you can skip it for 5.11 which is around the corner and
   have more time for review for 5.12. I've added more eyes in the review
   list.


All patches are based on linux next 20201211 after patch at [3] is
applied.
