Well, we cannot disable 4K support for all platforms, so I guess this refers only to IA64. IA64 can certainly be build with 4K support. I am not sure how well user space tools play with it. Better leave it selectable unless others on linux-ia64 have something to say on the issue. - 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/
