Thanks! This is Arnd's idea to come up with a common script
for all the architecture. This implementation is a groundwork to
solve Y2038 issue.

I was rebased with 4.19-rc8 before sending v2 (what I remember).

I would like Arnd's to comment on this as it is my first patch series. As I
mentioned in the cover letter this implementation done for 8 architecture-
alpha, ia64, m68k, microblaze, parisc, sh, sparc, and xtensa. Most of the
review are also done. mips and powerpc are *almost* completed. FYI,
The system call table generation script for IA64 merged in linux-next.
