Okay. If x32 marked as broken it does not hurt to the selftests as-is,
right?
I think sigreturn.c can stay as-is except for the comment referring to
x32.
syscall_numbering.c has plenty of x32 bits and I would go and remove
them once start removing the x32 bits. The reason for 1/2 in this series
is that the nolibc selftests expect x32 to be working on x86-64.

But this isn't the case here afaik. Now that I test it run into 
   https://lore.kernel.org/all/20261022142425.3Wx-RrU5@linutronix.de/

so the test is currently broken.

Did I understand you properly?
