From 39bef5bcf02a72fc5552dd20c61ec7ea65c85054 Mon Sep 17 00:00:00 2001 From: Keir Fraser Date: Thu, 20 Nov 2008 14:23:59 +0000 Subject: x86: make NR_IRQS build-time configurable While keeping the NR_IRQS default at 256 here, I think it would be a good thing to set it to a higher value to make sure no new mixing of irq and vector spaces slip in. Tested with NR_IRQS forced to 1024.
