| Subject: s390/irq: Only define synchronize_irq() on SMP |
| |
| From: Ben Hutchings <ben@decadent.org.uk> |
| |
| commit 690cec8e70c211d1f5f6e520b21a68d0306173b6 upstream. |
| |
| In uniprocessor configurations, synchronize_irq() is defined in |
| <linux/hardirq.h> as a macro, and this function definition fails to |
| compile. |
