It would be nice if they were more open about what they need/use.

Thanks. I'll publish the 4.12-based branch sometime next week.

At this stage I don't see much value in a linux-next based ILP32. I
would rather like to see a 4.13-rc3 based one, in preparation for a 4.13
branch once released.

The 4.12 link is ok. However, could you please post a 4.13-rcX based
series, maybe split in two so that a few generic patches can be merged
in 4.14? Given the reworking of the sigcontext code in 4.13, it would be
good to review the ILP32 changes in this area again.

Thanks.
