I put in a fair bit of work earlier this dev cycle to add MIPS to the
kgdb test suite. Unfortunately that left me catching up on a few other
things... or putting it another way I am late putting together the kgdb
tree for v5.6. It will be done by the weekend.

The first patch never got a formal Acked-by from the MIPS folks but they
commented positively so we can probably go ahead.
