[PATCHv4 17/19] arm64: use SYSCALL_DEFINE6() for mmap

From: Mark Rutland
Date: Mon Jul 02 2018 - 07:05:19 EST

We don't currently annotate our mmap implementation as a syscall, as we
need to do to use pt_regs syscall wrappers.

Let's mark it as a real syscall.

There should be no functional change as a result of this patch.
