This change causes the following compile errors on m68k:

spin_lock_irq
-> _spin_lock_irq
-> preempt_disable
-> inc_preempt_count
-> add_preempt_count
-> preempt_count
-> current_thread_info
-> task_thread_info
which needs the definition of struct task_struct.
The patch below fixes it by including <linux/sched.h> in
kernel/time/clocksource.c. But perhaps this is the right time to move
struct task_struct to its own include instead?
