 For the record, my test board has been restored to normal operation and I 
have now finished regression-testing with the `mips-mti-linux-gnu' remote 
target and its three ABIs, with no problems observed compared to results 
as at commit de6242d30757^.

 Thank you for getting the fix completed so quickly.
