True, The patch you mentioned here is the merged recently and I
created this patch series
few hours before that.

Yes. I have created the system call table generation support for 10
architecture including
sparc. Every architecture I validated the generated file with replaced
one and made sure
both are same. But still I expect some human errors. The one which I
missed was caught
by respective maintainers.
BTW, the error can be raised only one time, during the development.

syscall.tbl is the input to the script, so the developers has the
responsibility to fill the table
properly. I don't know, we have to write a script which has to be
smart enough to catch the
wrong syscall entries.
Thanks for your feedback.
