From 98e27a5c13badb5c56d9d1d6c8ec210753ac1195 Mon Sep 17 00:00:00 2001 From: Jamie Iles Date: Mon, 12 Dec 2011 20:17:37 +0000 Subject: [PATCH] ARM: picoxcell: don't reserve irq_descs All irq_desc's are now dynamically allocated so we don't need to statically reserve them. v2: - select SPARSE_IRQ and set .nr_irqs to NR_IRQS_LEGACY to skip ISA and IRQ 0.
