I actually worked on this last week and did a new series to convert
the old asm-generic/unistd.h header into the syscall.tbl format,
and change arm64 to use that.

You can find my work in the 'syscall-tbl' branch of my asm-generic
tree [1]. This has only seen light build testing so far, and is
probably still buggy, but most of the work is there. The missing
bits are the Makefiles for the other seven architectures using
asm-generic/unistd.h, and checking the output to ensure the
contents are still the same.

That sounds fine to me.
