I don't know. I would like to have responses. Ralf asked Maciej about old
systems and that came nowhere. Even rewrite - don't know what to do with that:
no lightweight SYNC or no SYNC at all - yes, it is still possible that SYNC on
some systems can be too heavy or even harmful, nobody tested that.

 I don't recall being asked; 

In http://patchwork.linux-mips.org/patch/10505/ the very last mesg exchange is:

Maciej,

do you have an R4000 / R4600 / R5000 / R7000 / SiByte system at hand to
test this?

 I should be able to check R4400 (that is virtually the same as R4000) 
next week or so.  As to SiByte -- not before next month I'm afraid.  I 
don't have access to any of the other processors you named.  You may 
want to find a better person if you want to accept this change soon.
