Hi!

quoted

Have a look at this commit that tries to deal with passing 64 bit
numbers to syscalls. On 32 bit ABI (but not on X32) these needs to be
split up (accordingly to machine endianity).

https://github.com/linux-test-project/ltp/commit/04afb02b4280a20c262054e8f99a3fad4ad54916

That is wrong, too.  That assumes that there will never be padding
words, which isn't true in the general case, either.

Well, it's still far better than the mess we had previously and it works
in most of the cases. However I would love to fix these correctly once
for all.

I really believe the proper fix is to use assembly syscall stubs.  In
klibc I build a fairly elaborate machinery to autogenerate such syscall
stubs for a variety of architectures.

Then it would be nice to share these between klibc and LTP (and possible
everybody else).
