    Subject[patch 088/101] kernel/time/clocksource.c needs struct task_struct on m68k

    From: Mathieu Desnoyers <>

    kernel/time/clocksource.c needs struct task_struct on m68k.

    Because it uses spin_unlock_irq(), which, on m68k, uses hardirq_count(), which
    uses preempt_count(), which needs to dereference struct task_struct, we
    have to include sched.h. Because it would cause a loop inclusion, we
    cannot include sched.h in any other of asm-m68k/system.h,
    linux/thread_info.h, linux/hardirq.h, which leaves this ugly include in
    a C file as the only simple solution.
