Subject: [PATCHv2 17/19] arm64: use SYSCALL_DEFINE6() for mmap
Date: Fri,  1 Jun 2018 12:24:39 +0100	[thread overview]
Message-ID: <20180601112441.37810-18-mark.rutland@arm.com> (raw)
In-Reply-To: <20180601112441.37810-1-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.
