Use
This is an internal call for OS use only and should not be used by user software.
Returns a number in the range [0, HAL_CPUCount) which identifies the current core. Typically this will just involve extracting the lower bits from the CP15 MPIDR register, however since core numbering is platform-specific this action must be performed by the HAL.
