genirq: Fix UP compile failure caused by irq_thread_check_affinity
Since genirq: Delegate irq affinity setting to the irq thread
(591d2fb02e
) compilation with
CONFIG_SMP=n fails with following error:
/usr/src/linux-2.6/kernel/irq/manage.c:
In function 'irq_thread_check_affinity':
/usr/src/linux-2.6/kernel/irq/manage.c:475:
error: 'struct irq_desc' has no member named 'affinity'
make[4]: *** [kernel/irq/manage.o] Error 1
That commit adds a new function irq_thread_check_affinity() which
uses struct irq_desc.affinity which is only available for CONFIG_SMP=y.
Move that function under #ifdef CONFIG_SMP.
