Subject: [PATCH 1/2] sh: remove nargs from __SYSCALL
Date:   Wed,  2 Jan 2019 21:07:24 +0530
Message-Id: <1546443445-21075-2-git-send-email-firoz.khan@linaro.org>
In-Reply-To: <1546443445-21075-1-git-send-email-firoz.khan@linaro.org>
References: <1546443445-21075-1-git-send-email-firoz.khan@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The __SYSCALL macro's arguments are system call number,
system call entry name and number of arguments for the
system call.

Argument- nargs in __SYSCALL(nr, entry, nargs) is neither
calculated nor used anywhere. So it would be better to
keep the implementaion as  __SYSCALL(nr, entry). This will
unifies the implementation with some other architetures
too.
