I also suggest to dump 'locore_jumpvec' away.  Make distictions
between processor dependent functionality (and parameters), target
hardware circuit specifics and particular kernel implemenation
dependent stuffs.  locore_jumpvec is a kitchen sink approach mixing
all of them.  This would end up with major surgery on arch/mips/, but
given situations of large diversity of MIPS processors it'd be
unavoidable anyway.
