OK, so: config WANT_PHYS_64BIT select PHYS_64BIT if !EMBEDDED config PHYS_64BIT default y if WANT_PHYS_64BIT ...and "select WANT_PHYS_64BIT" on boards that normally have 36-bit address maps? What about 86xx? It looks like PHYS_64BIT can't be enabled if it's sharing a kernel image with 82xx or 83xx (why these specific SoCs but not 603 in general?). -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
