From 10083072bfabc40bc47306e512c158c57cf55c2e Mon Sep 17 00:00:00 2001 From: Mark Maule Date: Fri, 14 Apr 2006 16:03:49 -0500 Subject: [PATCH] PCI: per-platform IA64_{FIRST,LAST}_DEVICE_VECTOR definitions Abstract IA64_FIRST_DEVICE_VECTOR/IA64_LAST_DEVICE_VECTOR since SN platforms use a subset of the IA64 range. Implement this by making the above macros global variables which the platform can override in it setup code. Also add a reserve_irq_vector() routine used by SN to mark a vector's as in-use when that weren't allocated through assign_irq_vector().
