Subject: [PATCHv5 19/21] arm64: use SYSCALL_DEFINE6() for mmap
Date: Wed, 11 Jul 2018 14:56:54 +0100	[thread overview]
Message-ID: <20180711135656.20670-20-mark.rutland@arm.com> (raw)
In-Reply-To: <20180711135656.20670-1-mark.rutland@arm.com>

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.
