[PATCH -rt] harirq.h: Define softirq_count() as OUL to kill buildwarning

From: Yong Zhang
Date: Thu Oct 13 2011 - 05:19:23 EST


kernel/lockdep.c: In function âprint_bad_irq_dependencyâ:
kernel/lockdep.c:1476:3: warning: format â%luâ expects type âlong unsigned intâ, but argument 7 has type âunsigned intâ
kernel/lockdep.c: In function âprint_usage_bugâ:
kernel/lockdep.c:2193:3: warning: format â%luâ expects type âlong unsigned intâ, but argument 7 has type âunsigned intâ

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);
