A sparc64 is unlikely to be short on memory, or is it ? What's wrong with always aligning on 128 bytes on sparc64 ? A runtime check would be expensive.
Maybe on arch FOO, target X needs no alignment when using PCI controller Y, but for PCI controller Z it does need alignment. - 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/
