Thank you for working on this problem.
The fix looks great to me.

Thank you.

While applying it I noticed few nits:
Applying: selftests/bpf: sync kernel headers and introduce arch support in Makefile
/w/bpf/.git/rebase-apply/patch:253: trailing whitespace.
        freg_t  fprs[NUM_FPRS];

        } lowcore;

} ptprot_area;
warning: 4 lines add whitespace errors.

Could you please fix those and resubmit ?

Sure will do.  For that I have to add a clean-up patch for the s390 ptrace.h
uapi header.

With that fixed feel free to add my
Acked-by: Alexei Starovoitov <ast@kernel.org>
to the patches.

Thank you very much, will do!

I've tested it on arm64 and don't see any issues.

I got a nice message from the build bot, I have some more work on that.
So will respin the series, add you Acked-by, and sent a v2 around.

When resubmitting could you please reduce cc-list, since this set
went into spam folder for me and I noticed it only in patchworks.

Will do... I just used what get_maintainers.pl told me :)
