Here are some of those on top of my mind.  And I am pretty sure I am missing 
others:

1) /proc/cpuinfo and some bootinfo.h change  (I think these two come from one 
change)
2) split of cache and tlb files
3) some kind of flush_cache_LSB() routines.

It is not big logically.  However, outside all the boards that are in oss 
tree, I can safely say there are at least twenty MIPS porting efforts going on 
at various stages.  Next time those people sync up with oss, they will find 
the missing symbol of bus_error_init().

It wasn't my intention to dampen your MIPS contribution.  In fact, I start to 
regret about my first email which now looks a little irresponsible.

If anything out of this thread can increase the awareness of open discussion 
and awareness of the existence of many boards which are not part of oss tree 
yet, I shall be happy.
