The patch titled
     kernel/time/clocksource.c needs struct task_struct on m68k
has been removed from the -mm tree.  Its filename was
     kernel-time-clocksourcec-needs-struct-task_struct-on-m68k.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
Subject: kernel/time/clocksource.c needs struct task_struct on m68k
From: Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca>

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.
