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, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
