Interesting timing! Have you seen this (which I'll send for 4.17, and leave 4.16 broken)? https://marc.info/?l=linux-kernel&m=151925667323732&w=2 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. Cheers James
