Potentially laziness/ignorance-of-feature? It looks like this feature started on x86_64 and then spread to arm*. Huge pages are weird on ia64 in that they have to be in a specific range of virtual addresses (region 4). But I don't see why that would prevent sharing pmd's. -Tony -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
