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. Signed-off-by: Zhang Yanmin <yanmin.zhang@intel.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
