Version 4 was back in August:
https://lists.gnu.org/archive/html/qemu-devel/2018-08/msg03745.html

Version 5 continues the file split via inclusion.  This incorporates
Laurent's suggestion to have a "def" file that is included twice to
generate both SyscallDef structures and fill in syscall_table's switch.

Again, this just converts a few syscalls as proof of concept.

Hi,

This series seems to have some coding style problems. See output below for

This series breaks on all targets LTP tests: getgroups01, pwritev02,
pwritev02_64, and fixes: semop02.

It also breaks more tests only with arm target.

I will bisect and review...

Thanks,
Laurent
