Subject: [PATCH 1/2] microblaze: remove nargs from __SYSCALL
Date: Wed, 2 Jan 2019 20:42:03 +0530 [thread overview]
Message-ID: <1546441924-20262-2-git-send-email-firoz.khan@linaro.org> (raw)
In-Reply-To: <1546441924-20262-1-git-send-email-firoz.khan@linaro.org>
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.
