Subject: [PATCH] ARM: Wire up the renameat2() syscall

The new renameat2() system call was only wired up for ARM causing:
 CALL    /home/ujfalusi/work/kernel/kernel.org-next-linux-next/scripts/checksyscalls.sh
<stdin>:1232:2: warning: #warning syscall renameat2 not implemented [-Wcpp]

Hi,

I have noticed this with linux-next.
