Register	protocol notification for ACPI processor ID mapping
Installs	a notify function to be called when the ACPI processor ID
mapping	protocol becomes available.
Register	protocol notification for SMBIOS data update
Installs	a notify function for the second SMBIOS data update channel.
Status	= gBS->RegisterProtocolNotify (
Register	protocol notification for the third data channel
Installs	a notify function for the PIRQ routing data.
Process	the ACPF table and update SMBIOS processor ID data.
This	callback handles the UMPT (Uncore Memory Protocol Table)
protocol	installation event.
The	SMBIOS data at table offset 0x9040 contains the processor
mapping	entries that map ACPI processor IDs to physical
Process	the PIRQ routing data and update SMBIOS interrupt tables.
This	callback handles the PIRQ protocol installation event.
The	PIRQ routing data at table offset 0x90C8 contains the
interrupt	routing entries for the LightningRidge platform.
