From dc29a3657b52ac687970d81d7194cf4238702124 Mon Sep 17 00:00:00 2001 From: Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca> Date: Sat, 10 Feb 2007 01:43:43 -0800 Subject: [PATCH] [PATCH] kernel/time/clocksource.c needs struct task_struct on m68k 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.
