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). > The window will be opened in less than a month, so I'd like to remind > it to you, and ask if you have any questions/requests related to > ILP32. Is it still realistic idea to take patches in 4.12? 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? -- Catalin
