Sorry, I wasn't present at Linaro Connect, so definitely not involved in
such decision.

BTW, it would be nice to have Arnd's ack on patch 2 (32-bit ABI:
introduce ARCH_32BIT_OFF_T config option).

4.12 is not realistic and I wouldn't commit to a specific kernel
version. Given the intrusiveness, such patches should sit in -next for
at least 3-4 weeks (i.e. merged in the arch tree around -rc3).

Anyway, I don't think the plan has changed since last time I stated it:

https://lkml.org/lkml/2016/12/5/333

I haven't got the chance to test these patches yet, run benchmarks (step
4). Also, the latest benchmarks I've seen were mostly for user space
while I'm more concerned with the user-kernel interface
(https://marc.info/?l=linux-arm-kernel&m=148690490713310&w=2). Is there
an up to date pre-built toolchain and a filesystem for ILP32?

On the glibc testing side, have the regressions been identified/fixed?
