Subject: hardirq.h: Define softirq_count() as OUL to kill build warning
From: Yong Zhang <yong.zhang0@gmail.com>
Date: Thu, 13 Oct 2011 17:19:09 +0800
kernel/lockdep.c: In function ‘print_bad_irq_dependency’:
kernel/lockdep.c:1476:3: warning: format ‘%lu’ expects type ‘long unsigned int’, but argument 7 has type ‘unsigned int’
kernel/lockdep.c: In function ‘print_usage_bug’:
kernel/lockdep.c:2193:3: warning: format ‘%lu’ expects type ‘long unsigned int’, but argument 7 has type ‘unsigned int’
kernel/lockdep.i show this:
printk("%s/%d [HC%u[%lu]:SC%u[%lu]:HE%u:SE%u] is trying to acquire:\n",
curr->comm, task_pid_nr(curr),
curr->hardirq_context, ((current_thread_info()->preempt_count) & (((1UL << (10))-1) << ((0 + 8) + 8))) >> ((0 + 8) + 8),
curr->softirq_context, (0U) >> (0 + 8),
curr->hardirqs_enabled,
curr->softirqs_enabled);
