Subject: [PATCH v1 1/4] xtensa: move SYS_XTENSA_* macros to non uapi header
Date:   Thu,  1 Nov 2018 19:26:18 +0530
Message-Id: <1541080581-4072-2-git-send-email-firoz.khan@linaro.org>
In-Reply-To: <1541080581-4072-1-git-send-email-firoz.khan@linaro.org>
References: <1541080581-4072-1-git-send-email-firoz.khan@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

All the SYS_XTENSA_* macros used by sysxtensa syscall
handlers are resides in the uapi header file move to
non uapi header asm/unistd.h as it is not used by any
user space applications.

It is correct to keep these macros in non uapi header
file asm/unistd.h while uapi/asm/unistd.h must hold
information only useful for user space applications.

One of the patch in this patch series will generate
uapi header file. The information which directly used
by the user space application must be present in uapi
file.
