[PATCHv3 17/19] arm64: use SYSCALL_DEFINE6() for mmap

From: mark.rutland@arm.com (Mark Rutland)
Date: 2018-06-18 12:04:16
Also in: linux-fsdevel
Subsystem: arm64 port (aarch64 architecture), the rest · Maintainers: Catalin Marinas, Will Deacon, Linus Torvalds

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.
