Arm64 directly uses tools/scripts/syscall.tbl, I can confirm that this
patch works for Arm64 after updating tools/scripts/syscall.tbl.

Note, tools/perf/arch/arm64/entry/syscalls/syscall_32.tbl is not
synchronized.  This is fine for me, as perf generates the syscall array
using tools/perf/arch/arm/entry/syscalls/syscall.tbl instead.  We can
consider to remove tools/perf/arch/arm64/entry/syscalls/syscall_32.tbl
as it is not used in perf, but this is not in this patch's scope.

For Arm and Arm64:
