    Subject[PATCH 3.18 101/108] alpha: Fix Eiger NR_IRQS to 128
    Date
    3.18-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Meelis Roos <mroos@linux.ee>

    commit bfc913682464f45bc4d6044084e370f9048de9d5 upstream.

    Eiger machine vector definition has nr_irqs 128, and working 2.6.26
    boot shows SCSI getting IRQ-s 64 and 65. Current kernel boot fails
    because Symbios SCSI fails to request IRQ-s and does not find the disks.
    It has been broken at least since 3.18 - the earliest I could test with
    my gcc-5.

    The headers have moved around and possibly another order of defines has
    worked in the past - but since 128 seems to be correct and used, fix
    arch/alpha/include/asm/irq.h to have NR_IRQS=128 for Eiger.

    This fixes 4.19-rc7 boot on my Force Flexor A264 (Eiger subarch).
