Zhou, please > share your new email. This is the 4.19-based update: https://github.com/norov/linux/tree/ilp32-4.19 Syscall machinery is rewritten in C in mainline kernel, ILP32 is aligned with it. The following patches are mostly affected: arm64: ilp32: introduce ilp32-specific 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: introduce syscall table for ILP32 arm64: ilp32: share aarch32 syscall handlers 4.18 branch from Catalin is here: https://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git/log/?h=3Dst= aging/ilp32-4.18 Yury
