Subject: [PATCH] IRQ: Change __softirq_pending to unsigned int in
	asm-generic/hardirq.h.

Since the beginnings in aafe4dbed0bf6cbdb2e9f03e1d42f8a540d8541d
include/asm-generic/hardirq.h defined __softirq_pending as unsigned long
which is different from other architectures for no apparent good reason
and was causing the following warning:

kernel/time/tick-sched.c: In function 'tick_nohz_stop_sched_tick':
kernel/time/tick-sched.c:261: warning: format '%02x' expects type 'unsigned int', but argument 2 has type 'long unsigned int'

Reported and initial patch by Wu Zhangjin <wuzhangjin@...il.com>.

Signed-off-by: Ralf Baechle <ralf@...ux-mips.org>

Tested on a big endian 64-bit MIPS SMP system.
