Was just wondering why the (2.4.19) kernel compilation for MIPS4K systems
appears to be using the "-mips2" compiler setting - shouldn't it be using
-mips4 or -mips32 to get the full instruction set?
Thanks.

Because we want MIPS II only ;-)

There are serious problems with the use of 64-bit stuff in the 32-bit
kernel, so we can't use mips3, mips4 or mips64.  -mips32 works but is not
supported by all toolchains.  Anyway, mips32 doesn't deliver much that isn't
already part of MIPS II.
