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()
