Hi Catalin, all (Exclude Bamvor as his email became invalid) This is 4.15-based kernel. https://github.com/norov/linux/commits/ilp32-4.15 I tested it with LTP, no regressions found. Kernel v4.15 incorporates SVE series from Dave Martin, so I updated ILP32 patches to agree with it. SVE-related changes are mostly in patches: arm64: ilp32: introduce ilp32-specific handlers for sigframe and ucontext arm64: signal32: move ilp32 and aarch32 common code to separated file arm64: signal: share lp64 signal structures and routines to ilp32 arm64: ilp32: add sys_ilp32.c and a separate table (in entry.S) to use it Dave kindly reviewed that patches and proposed improvements: https://www.spinics.net/lists/arm-kernel/msg629221.html There's no ABI-related changes proposed, or urgent fixes; so I'll rework signal subsystem during 4.16 cycle. Are there any news with upstreaming this series?
