MPIDR_LEVEL_SHIFT() differs between 64 and 32 bit. > For 64 bit :- aff_lev3 aff_lev2 aff_lev1 aff_lev0 |________|________|________|________|________| 40 32 24 16 8 0 For 32 bit :- aff_lev3 aff_lev2 aff_lev1 aff_lev0 |________|________|________|________| 32 24 16 8 0
As discussed with Michal, AFF3 doesn't exist for 32-bit. So it is not clear to me what we are gaining by moving the macros.
