/// ## Local SAPIC Structure
///
/// The Processor local SAPIC structure is very similar to the processor local APIC structure.
/// When using the SAPIC interrupt model, each processor in the system is required to have a Processor Local SAPIC record in the MADT, and a processor device object in the DSDT.
/// OSPM does not expect the information provided in this table to be updated if the processor information changes during the lifespan of an OS boot.
/// While in the sleeping state, processors are not allowed to be added, removed, nor can their SAPIC ID or Flags change.
/// When a processor is not present, the Processor Local SAPIC information is either not reported or flagged as disabled.
