Since the beginnings in aafe4dbe
("asm-generic: add generic versions of common headers") the generic
version of <asm/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@gmail.com>.

[ Arnd points out that we really should make sure parisc and alpha are
  ok with this, since they have also been converted to use the generic
  hardirq.h file. But neither seems to use it, although parisc does
  build a IRQSTAT_SIRQ_PEND #define into asm-offsets - but that also
  appears unused..    - Linus ]
