I would have liked to think the same; but the way linux-record.h
addresses all the architecture, the enum sycall, is defiend
generically.
what I think is define it in arch files, as syscalls are partially
dependent on arch, though they follow posix standard.
so each arch file would have their own map, compare to current generic
map in linux-record.h
Regards,
Oza.
