| H A D | irq_srm.c | 70b66cbf Thu Jan 15 15:51:17 CST 2009 Ivan Kokshaysky <ink@jurassic.park.msu.ru> alpha: nautilus - fix compile failure with gcc-4.3
init_srm_irq() deals with irq's #16 and above, but size of irq_desc
array on nautilus and some other system types is 16. So gcc-4.3
complains that "array subscript is above array bounds", even though
this function is never called on those systems.
This adds a check for NR_IRQS <= 16, which effectively optimizes
init_srm_irq() code away on problematic platforms.
Thanks to Daniel Drake <dsd@gentoo.org> for detailed analysis
of the problem.
