You should note that your chosen system call number of 391 is temporary
here and can't be relied upon as we have to wire up the new
copy_file_range() call on ARM (which I've just committed the patch for.)

I'd much prefer the wiring up to be either an entirely separate patch
(which must be submitted to me, and I'll merge between -rc1 and -rc2
along with any other syscall updates) or you leave the wiring up to me.

This is so that I can ensure that (a) system calls numbers are not
duplicated and (b) ensure that we follow the same logical order as x86
where possible.

Thanks.
