For 32-bit the config is nlm_xlr_defconfig in the source tree. Let me know if
you need any further info.

Would you be able to dump out the TLB handlers in this configuration,
per David's suggestion?

The current linux-mips queue works for me, and I don't have the old source
or binaries with me anymore. You surely should be able build with
nlm_xlr_defconfig and see if the rixi is enabled in the build, if you want
any config register dump on the CPU, please let me know.

The problem is that we don't have your hardware to test anything on.

Kevin's patches are a good cleanup, but we cannot use them if they break things. So the ideal situation would be for people maintaining the failing ports to help figure out where they fail.
