Subject: [PATCH 2/2] alpha: generate uapi header and syscall table header files
Date:   Wed,  2 Jan 2019 20:36:59 +0530
Message-Id: <1546441619-19977-3-git-send-email-firoz.khan@linaro.org>
In-Reply-To: <1546441619-19977-1-git-send-email-firoz.khan@linaro.org>
References: <1546441619-19977-1-git-send-email-firoz.khan@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Unified system call table generation script must be run to
generate unistd_32.h and syscall_table.h files. This patch
will have changes which will invokes the script.

This patch will generate unistd_32.h and syscall_table.h
files by the syscall table generation script invoked by
alpha/Makefile and the generated files against the removed
files must be identical.

The generated uapi header file will be included in uapi/-
asm/unistd.h and generated system call table header file
will be included by kernel/systbls.S file.
