This is the 4.13-rc3 - based branch:
https://github.com/norov/linux/tree/ilp32-4.13-rc3

Patches prior to 52315bc30f4967 ("arm64: ilp32: add documentation on
the ILP32 ABI for ARM64") are looking like generic. 

Note that this series includes the patch "ptrace: Add compat
PTRACE_{G,S}ETSIGMASK handlers":
https://patchwork.kernel.org/patch/9817343/

It is still under discussion in maillist. If it will be rejected, we'd
rework arm64 ptrace accordingly.

Thanks, I forgot to mention it in previous email. Changes are mostly located in
patches d87e8ed73d59 ("arm64: signal: share lp64 signal structures and routines
to ilp32") and 99c30e5df3f4 ("arm64: ilp32: introduce ilp32-specific handlers
for sigframe and ucontext"). All reviews are appreciated.
