Message-ID: <20100318213054.GB4989@x200>
Date: Thu, 18 Mar 2010 23:30:54 +0200
From: Alexey Dobriyan <adobriyan@...il.com>
To: torvalds@...ux-foundation.org
Cc: linux-kernel@...r.kernel.org, linux-arch@...r.kernel.org
Subject: [PATCH v2] headers: remove mm_types.h from sched.h
* remove mm_types.h inclusion from sched.h
* move init_mm declaration not to mm.h but to mm_types.h
to overcome header loops on sparc64
* move mm_struct related stuff to mm.h
* fix fallout
Signed-off-by: Alexey Dobriyan <adobriyan@...il.com>
