>Description:
Althoug arch/mips/locore.h says that it supports MIPS I and MIPS III,
there is no definition for VR4300(NEC) architecture.  To enable use of
VR4300, just add #ifdef case so that MachFlushDCache be defined
as mips3_FlushDCache.  I am sorry that my code(actually diff result) is old,
but I am sure that the current code(/src/sys/arch/mips/locore.h) also have
same problem. (I checked the code on cvsweb)

State-Changed-Why:
New thorpej-mips-cache branch has been merged and VR4300 is handled
as well as R4000 without L2 in current mips cache code.
Is it ok to close this PR?
