[<prev] [next>] [day] [month] [year] [list]

Message-ID: <20061017155526.GA9888@linux-mips.org>
Date:	Tue, 17 Oct 2006 16:55:26 +0100
From:	Ralf Baechle <ralf@...ux-mips.org>
To:	Andrew Morton <akpm@...l.org>, linux-kernel@...r.kernel.org
Subject: [PATCH] Make <linux/personality.h> userspace proof

<linux/personality.h> contains the constants for personality(2) but also
some defintions that are useless or even harmful in userspace such as
the personality() macro.

Signed-off-by: Ralf Baechle <ralf@...ux-mips.org>
