The defconfig already enables CONFIG_PHYS_64BIT for the P1022DS and all other 85xx parts. If you look at the Kconfig, you'll see that most boards don't enable it. So by default, everything is 64-bit capable. Adding the Kconfig option will *prevent* anyone from creating a 32-bit kernel. This is my problem with the patch. -- Timur Tabi Linux kernel developer at Freescale
