SPRG0–SPRG3, SPRs 272-275, are provided for general operating system use, such as fast-state saves
and multiprocessor-implementation support. SPRG0–SPRG3 are shown below.

Software may load a unique physical address in this register to identify an area of memory reserved for use
by the exception handler. This area must be unique for each processor in the system.
This register may be used as a scratch register by the exception handler to save the content of a GPR. That
GPR then can be loaded from SPRG0 and used as a base register to save other GPRs to memory.
This register may be used by the operating system as needed.
This register may be used by the operating system as needed.
