You're changing the layout of a data structure that is shared with the firmware. Using a 32bit int here is fine when the driver sets the correct dma mask or only stuffs pci_alloc_consistent() memory in there (i think it's the later here) Even though the driver prints lots of warnings at compile time it actually works on AMD64 as is. But in many cases you should use megaraid2.c instead of megaraid.c. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
