Message-ID: <20080618003650.GO25911@cs181133002.pp.htv.fi>
Date:	Wed, 18 Jun 2008 03:36:50 +0300
From:	Adrian Bunk <bunk@...nel.org>
To:	lethal@...ux-sh.org
Cc:	linux-sh@...r.kernel.org, linux-kernel@...r.kernel.org
Subject: [2.6 patch] sh/kernel/ cleanups

This patch contains the following cleanups:
- make the following needlessly global code static:
  - cf-enabler.c: cf_init()
  - cpu/clock.c: __clk_enable()
  - cpu/clock.c: __clk_disable()
  - process_32.c: default_idle()
  - time_32.c: struct clocksource_sh
  - timers/timer-tmu.c: struct tmu_timer_ops
- remove the following unused functions (no CONFIG_BLK_DEV_FD on sh):
  - process_{32,64}.c: disable_hlt()
  - process_{32,64}.c: enable_hlt()

Signed-off-by: Adrian Bunk <bunk@...nel.org>
