From 9f271d576a79f74a543c4099a014d8d4eafa737d Mon Sep 17 00:00:00 2001 From: "Zhang, Yanmin" Date: Fri, 9 Feb 2007 11:29:51 +0800 Subject: ATA convert GSI to irq on ia64 If an ATA drive uses legacy mode, ata driver will choose 14 and 15 as the fixed irq number. On ia64 platform, such numbers are GSI and should be converted to irq vector. Below patch against kernel 2.6.20 fixes it.
