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.
