[PATCH] ARM: add copy_file_range system call

From: Arnd Bergmann <arnd@arndb.de>
Date: 2016-01-22 13:48:17

The copy_file_range system call was added in linux-4.5 needs to
be added to the system call tables on all architectures.

This is the change for arch/arm.

Thanks, but as ever I much prefer to update the syscall table myself
after -rc1.
