scripts/checkpatch.pl reports 30 errors and 24 warnings on your patch.
Also, you didn't CC maintainers, so they most probably missed your
patch in LKML noise. I CCed some of them here.
scripts/get_maintainers.pl should point you to proper persons.

arm64/ilp32 and arm64/lp64 is the single platform, and so lp64 and
ilp32 parts share the same installed kernel headers. That's why I had to
introduce #ifdef magic here and in other kernel and glibc headers.

Arm32 is different platform, so I don't understand what the benefit
in joining headers. Could you explain it in details.

Your patch has 2880 lines. It's quite difficult to read it at once
(and I didn't do that). Is it possible split in into the series?
