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).
