 There is hardly any need as generally KSEG0/KSEG1 and XPHYS mappings 
fulfil the need and are always available, even before paging has been 
initialised.  Some 32-bit systems with devices outside low 512MB of 
physical address space could potentially benefit though.  I recall some 
Alchemy systems may fall into this category.
