Interesting timing! Have you seen this (which I'll send for 4.17, and
leave 4.16 broken)?

The Meta port is essentially unused and for a while I have only looked
at it when something went wrong. PURE's Linux based digital radios I
believe were never updated to 3.10. The fact that the GCC port wasn't
upstreamed before the MIPS acquisition meant it was always a ticking
time bomb (though binutils was upstreamed).

Sad really, given that at least 9 years of effort went into the port
before permission was finally given to upstream it, and within a week or
so of the first patchset the intention to acquire MIPS was announced.

FWIW, my experience was that upstreaming the port caught a whole lot of
issues (Al Viro's review of signal handling alone was tremendously
valuable), and drastically reduced the effort required to forward port
to each new kernel version. Updating an out of tree arch tends to result
in a lot of runtime failures that require digging, which reduced
drastically once the port was upstreamed.
