Subject: [PATCH 1/4] sparc: Move __IGNORE* entries to non uapi header
Date: Tue,  4 Sep 2018 10:11:24 +0530	[thread overview]
Message-ID: <1536036087-15260-2-git-send-email-firoz.khan@linaro.org> (raw)
In-Reply-To: <1536036087-15260-1-git-send-email-firoz.khan@linaro.org>

All the  __IGNORE* entries are resides in the uapi header
file and it is not used by any user space applications.

One of the patch in this patch series will generate the
uapi header file and system call table file. So if we move
all the __IGNORE* entries to non uapi header, it will simplify
the uapi header and system call table file generation script.

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