Subject: [PATCH] Fix build error with !SMP && !GENERIC_HARDIRQS

When compile kernel with !SMP && !GENERIC_HARDIRQS we are have
following error:
  CC      kernel/irq/manage.o
kernel/irq/manage.c:41: error: expected identifier or '(' before 'asm'

This error appears because header contain other definition for
synchronize_irq in include/linux/hardirq.h.
extern void synchronize_irq(unsigned int irq);

This patch fix this problem.
