Subject: [PATCH] X86:  Change the default value of nr_irqs from 32 to NR_IRQs

From: Alex Nixon <alex.nixon@...rix.com>
Date: Tue, 19 Aug 2008 17:49:37 +0100
Subject: [PATCH] X86:  Change the default value of nr_irqs from 32 to NR_IRQs

If the number of discovered IRQs is suspiciously low, this patch causes the number reported to default to NR_IRQS, rather than 32.  NR_IRQS has already been defined to be a sensible value for the current system (in particular, at least 224 when paravirtualisation is involved).
