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

    From: "Zhang, Yanmin" <yanmin_zhang@linux.intel.com>

    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.
