The patch titled
alpha: nautilus - fix compile failure with gcc-4.3
has been removed from the -mm tree. Its filename was

This patch was dropped because it was merged into mainline or a subsystem tree

Subject: alpha: nautilus - fix compile failure with gcc-4.3
From: Ivan Kokshaysky <ink@xxxxxxxxxxxxxxxxxxxx>
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@xxxxxxxxxx> for detailed analysis
of the problem.
