[patch 100/101] ATA: convert GSI to irq on ia64

From: Greg KH
Date: Wed Mar 07 2007 - 12:20:05 EST



From: "Zhang, Yanmin" <yanmin_zhang@xxxxxxxxxxxxxxx>

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.
